UltraClean™ Blood DNA Isolation Kit
(PROCESSES 1,000 ml OF BLOOD)
INTRODUCTION
Use this kit for isolating high quality genomic, mitochondrial,
or viral DNA from 300 µl,3 ml or 10 ml of whole blood. Scale up the
protocol to process any volume of blood up to1,000 ml. DNA is ready
for restriction digest, amplification, hybridization,
sequencing,and cloning applications*.
The UltraClean™ Blood DNA Isolation Kit is designed to isolate
high molecular weightgenomic DNA from whole blood, buffy coat, bone
marrow, cultured cells, buccal swabs and other body fluids. This
kit is solution based and does not use spin filters. As a result,it
is possible to isolate high molecular weight DNA, greater than 100
kb.
SUMMARY
The yield and quality of DNA can vary greatly depending on the
individuals or other sources(bone marrow, non-human) and storage of
blood. Reduced yields and poor quality may occur ifsamples are
collected, stored or handled improperly.
PROCEDURE
Mammalian blood is composed of both non-nucleated red blood
cells (RBC) and nucleated white blood cells (WBC). Only the WBCs
contain DNA. To isolate cleangenomic DNA, the RBCs are first
preferentially lysed in a hypotonic buffer. The WBCs are pelleted
to separate them from the debris. Then they are extracted in a
bufferwith anionic detergent that stabilizes the DNA by preventing
DNase activity. RNase is used to remove RNA and protein is removed
with a precipitation step. The free genomic DNA is recovered using
isopropanol precipitation, washed with 70% ethanol toremove excess
salt, and resuspended in TE buffer to ensure long term stability at
-80oC.Because the procedure is so gentle, the DNA recovered will be
of high molecular weight.

HUMAN AND MAMMALIAN WHOLE BLOOD, BONE MARROWAND BUFFY COAT
SAMPLE COLLECTION AND HANDLING
WHOLE BLOOD AND BONE MARROW
1. If possible, collect whole blood and bone marrow in EDTA
tubes to reduceDNA degradation. However, other anticoagulants such
as ACD (citrate) andheparin may also be used successfully.
2. Store fresh samples at 4°C for up to 5 days for highest
yields. Blood will be stable for several months and provide
sufficient DNA for most applications suchas PCR.
3. Frozen samples are stable at -80°C for at least two years.
Before use, thaw quicklyin a 37°C water bath and keep sample on ice
until use.
BUFFY COAT
For DNA extraction, EDTA tubes are preferred to prevent DNA
degradation. However,other anti-coagulants, such as ACD or heparin
may also be used. Store fresh samples at 4°C.
Centrifugation Method:
1. To obtain the WBC layer, centrifuge whole blood at
1,500-2,000 x g (with thebreak off) for 10-15 minutes at room
temperature. The blood will separate intoplasma at the top and red
blood cells at the bottom with a white interfacebetween them called
the buffy coat.
2. Remove the upper plasma layer with a Pasteur pipette to
within 1 mm of the WBC layer. Discard the plasma if you are not
using it for other studies.
3. Using the Pasteur pipette, carefully suction off the white
layer in as small a volume as possible. Contamination with some of
the RBCs is expected.
4. Count the cells using a hemacytometer.Wash with PBS and
distribute into singleuse aliquots and centrifuge to pellet. Cells
may be frozen or used immediately for extraction.
Ficoll-Hypaque Method (Fisher Scientific catalog# NC
9524199):
1. Add 3 ml of Ficoll to a 10 ml round bottom or 15 ml Falcon
tube.
2. Layer 3 ml of whole blood on top of the Ficoll layer by
pouring carefully downthe side of the tube. Do not mix the Ficoll
with blood.
3. Centrifuge at 2,000 x g (with the break off) for 15 minutes
at 4°C or room temperature.
4. The buffy coat will be at the interphase between the upper
plasma layer and the lower RBC layer. Use a Pasteur pipette to
remove the interphase layer containing the WBCs.
5. Wash the cells in PBS twice and count using a hemacytometer.
Aliquot for single use before freezing.

HELPFUL HINTS FOR WORKING WITH LARGE NUMBERS OF SAMPLES
The following are hints for high-throughput sample processing
using the UltraClean™ Blood DNA Isolation Kit. Please contact MO
BIO Technical Services with any questions or for additional
information.
1. Use multi-channel pipettors to dispense Solution G1 (RBC
Lysis Solution),Solution G2 (Cell Lysis Solution), Solution G3
(Protein PrecipitationSolution), 100% Isopropanol, 70% Ethanol and
Solution G4 (DNA Hydration Solution). Using Repipettors helps
prevent contamination ofreagents and saves time.
2. Pre-aliquot Solution G1 (RBC Lysis Solution) and 100%
Isopropanol.
3. Lyse the cells in Solution G2 (Cell Lysis Solution) using a
vortex instead of pipetting.
4. Use a multi-tube vortex to vortex 24 samples at once (vortex
adapter for Genie 2(220 V: cat # 13111-V-220).
5. Add RNase A Solution to Solution G2. RNase A is stable in
Solution G2 for atleast 8 weeks at room temperature.
6. Precipitate the multiple samples with 100% Isopropanol
simultaneously byinverting all samples in the rack.
7. After rehydration, transfer samples purified in 15 ml or 50
ml centrifuge tubesto 2 ml microcentrifuge tubes.
8. A rotator may be used to gently mix samples during
incubations in Solution G1,100% Isopropanol, and Solution G4.

PROTOCOL – DNA PURIFICATION FROM BONE MARROW CELLS
NOTE: DNA purification from bone marrow cells requires the use
of Proteinase K Solution (20 mg/ml); MO BIO catalog# 1222-2.
SAMPLE PREPARATION
See Sample Collection and Handling section (page 5).
BONE MARROW CELL COLLECTION
Wear eye protection. Use this procedure to flush marrow cells
from small sections ofmouse bones. The following protocol is
optimized for 4 – 8 mouse femur bone shafts. Ifyou already have a
bone marrow cell pellet, start with the Cell Lysis step. If you
have marrow cells in suspension, pellet cells (steps 5 and 6
below).NOTE: You will need a sterile solution of phosphate buffered
saline (PBS). Also useful is
a cell strainer: BD Falcon catalog# 352350.
1. Scrape away tissue with sterile scalpel until bone is free of
any tissue. Using sterile scissors, cut off both rounded ends of
the bone. Cut as close to the socketas possible. Avoid shattering
the shaft.
2. Place bone in clean Petri dish containing PBS to keep bone
moist until ready to process.
3. Using sterile forceps or a hemostat, remove the bone shaft
and hold over a clean60 mm Petri dish. Using a 3 cc syringe and
needle (25 gauge) filled with sterilePBS push the needle into the
marrow and flush marrow cells out through theopposite end of the
bone shaft. Bone should lose its pinkish red color andbecome white
or translucent when the marrow has been completely removed.
4. Pipet the solution containing cells into a 50 ml conical tube
(for optimal resultsstrain cell material through a cell strainer to
remove any large particles). To maximize the number of cells
collected, be sure to rinse the cell strainer and Petri dish with
extra PBS.
5. Centrifuge at low speed at 1,400 rpm (400 x g) for 5 minutes
at room temperature.
6. Carefully discard the supernatant without disturbing the
pellet.
7. Centrifuge again at 400 x g for 1 minute and carefully remove
all traces of remaining supernatant.

FREQUENTLY ASKED QUESTIONS (FAQ’S) FOR ULTRACLEAN™ BLOOD DNA
ISOLATION KIT USERS
PROTOCOL QUESTIONS
1. My starting material is different than the sample types
mentioned in the MO BIO protocols. Can I still use the MO BIO
reagents from the kit?
Yes. Some tough to lyse samples such as mucous body secretions,
semensamples, etc. will require some pretreatments. Please check
with our TechnicalServices Department for more information.
2. Should I use Glycogen? If so, when should I use it?
Glycogen should be used during the DNA precipitation step if
expected yield isless than 2 µg as recommended in the Buccal Cell
Protocol. Use with samplesthat may result in a low yield of DNA
(for example low numbers of buccal cells,compromised samples and
body fluids).
3. My centrifuge settings are in RPM, how can I convert it in to
g-force?
All centrifuge steps are described in g-force. RPM and g-force
are two differentunits. Make sure samples are centrifuged at the
correct g-force. Failure to do somay result in lower DNA yields,
protein contamination or even loss of pellets.Use the equation
below to set the centrifuge to ensure the exact spinning
speed:g-force= 1.12 x r x (rpm/1000)2.NOTE: r = radius of rotor in
millimeters from center of rotor to center of tube cavity.
4. There is still some liquid in the tubes after the 10 minute
drying period.Should I let them dry for a longer time?
If drying the DNA samples for 10 minutes is not sufficient,
drying can beextended for a slightly longer period without
affecting the hydration (1-2 hours).Avoid overnight drying; this
might result in difficulty in resuspending DNA inthe hydration
buffer.
KIT QUESTIONS
1. Where can I buy the alcohol solutions: 70% Ethanol and 100%
Isopropanol?
Both of the alcohol solutions may be purchased by either
directly contacting MO BIO or your local MO BIO distributor. Please
see below for the catalognumbers: Cat # 12000-100-6 (70% Ethanol,
30 ml bottle), Cat # 12000-100-5(100% Isopropanol, 33 ml
bottle).
2. What are the ingredients and formulation of the reagents?
All the formulations of the reagents in the UltraClean™ Blood
DNAIsolation Kit are proprietary except for Solution G4 (DNA
Hydration Solution) which is 10 mM Tris, 1 mM EDTA pH 8.0. Please
refer to the MSDS for safety information.
-
26
3. My reagents were frozen when I received them. Can I still use
them?
Yes. Once you thaw the reagents and mix them well, you can use
them as normal.If any reagent has formed a precipitate, heat to
65°C until clear.
4. The Glycogen and/or the RNase A Solution were left out at
room temperature. Can I still use them?
Yes. However, make sure to place these items at their correct
storage temperature.
Please see below for more information:a. RNase A – Stability and
storage: The enzyme is stable for years stored as a
refrigerated dry powder or frozen in solution; refrigerated
solutions are stablefor weeks.NOTE: RNase A aggregates upon
lyophilization and storage.
b. PROTEINASE K – Stability and storage: Lyophilized: 1-2
yearsAqueous stock solutions: 72 hours at +4°C or 4 months as a
frozen solution.Concentrated stock solutions: 1-2 years at
-20°C.
c. GLYCOGEN – Storage: Solution should be aliquoted into
suitable volumes and stored at -20°C.
5. There is a white flaky precipitate, in the Cell Lysis
Solution. Can I still use this solution?
Yes. The SDS present in Solution G2 (Cell Lysis Solution) will
precipitate atcooler temperatures. Warm the Cell Lysis Solution in
a water bath at 55-65°Cuntil the precipitate re-dissolves. Mix well
before use.
6. Can I get a Material Safety Data Sheet (MSDS)?
The MSDS sheets are available on our website. Each product page
has a corresponding MSDS. You can also request them through
Technical Services.These can be sent via fax, email or mail.
7. Can I get a Certificate of Analysis (C of A) for the
UltraClean™ Blood DNA kit?
Yes.You can request a C of A from MO BIO’s Technical Services.
Please makesure to provide the catalog number and lot number of the
solution and/or kit C of A being requested. This C of A can be
faxed, e-mailed or mailed to you.

TROUBLESHOOTING GUIDE
RBC LYSIS STEP
1. The lysis of the red blood cells with Solution G1 (RBC Lysis
Solution) was not complete.
The sample contains a higher than average number of Red Blood
Cells(RBC). To lyse the cells completely, repeat the RBC lysis by
adding 3 parts ofSolution G1 (RBC Lysis Solution) to 1 part of
sample, incubate for 10 minutesat room temperature, then centrifuge
as recommended in the manual for yourspecific protocol.
2. The white cell pellet is loose after centrifugation.
a. Increase the centrifugation time from 2 minutes to 5 minutes
if working withlarge volume samples (15 ml or 50 ml tube).
b. The speed and time for the centrifuge might not be set
correctly. Check the centrifuge settings. Please contact MO BIO’s
Technical Services for help.
CELL LYSIS STEP
1. The cells isolated from a Ficoll gradient were not completely
lysed.
The lysis was incomplete because the Ficoll was not sufficiently
removed. Washcells with phosphate buffered saline (PBS) to remove
the Ficoll before addingSolution G2 (Cell Lysis Solution). Incubate
the lysate at 65°C to complete thelysis if needed.
2. The cells were not completely lysed.
a. The system is overloaded with cells due to the fact that the
amount of SolutionG2 (Cell Lysis Solution) was insufficient
compared to the amount of cells. TheCell Lysis Solution will become
highly viscous and result in the clumping of cells.The lysis of
cells can be completed by adding more Solution G2. To
avoidincomplete cell lysis, count the number of cells using a
hemacytometer or othercell counter based method before starting
cell lysis.
b. Cells are not completely re-suspended before adding the
Solution G2 (Cell LysisSolution) resulting in cell clumps. For
lysing the cells in clumps, incubate thesample at 37°C with gentle
mixing until the sample is homogeneous.Alternatively, add
Proteinase K Solution to a final concentration of 100 µg/mland
incubate the sample at 55°C (1 hour to overnight) to dissolve the
cell clumpsat a faster rate and complete the lysis.

28
PROTEIN PRECIPITATION STEP
Problems with the protein pellet: soft, loose or no pellet
There are three different reasons why this may occur:
1. The centrifuge settings are not correct.
Make sure that the centrifuge speed is set to the recommended
g-force called forin the protocol.
- If you are using microcentrifuge tube preps, set the
centrifuge speed to maximum.
- If you are using a table top or any centrifuge other than a
microcentrifuge, setthe speed to 2,500 x g. If this g-force can not
be attained by the centrifuge,increasing centrifugation time can
achieve the same total g-force. For example,if there is a
requirement of 2,500 x g for 5 minutes for a particular
protocol(25,000 x g = Total g-force x minutes) and the centrifuge
only can achieve 1,000 x g, then it will be necessary to increase
the spin time to 25 minutes.
RPM and g-force are two different units. Make sure to spin the
samples at theappropriate speed. If not, you might get a lower
yield, protein contamination oreven loose pellets.
Use the equation below to set your centrifuge to ensure the
correct spinningspeed. g-force = 1.12 x r x (rpm/1000)2.
NOTE: r = radius of rotor in millimeters from center of rotor to
center of tube cavity.
2. The cell lysate and Solution G3 (Protein Precipitation
Solution) were not mixed properly.
Vortex as thoroughly as possible for 20 seconds as specified in
the protocol.
3. A loose protein pellet is a sign that the sample was not
cooled adequately (20-22°C) prior to the addition of Solution G3
(Protein PrecipitationSolution).
Before adding Solution G3, cool samples to room temperature or
below. Followthese three steps to achieve a tighter protein
pellet:
a. Repeat the vortexing for an additional 20 seconds to
uniformly mix the ProteinPrecipitation Solution with the cell
lysate.
b. Incubate the sample on ice for 10-15 minutes. (This should
help in the formationof a tighter pellet.)
c. Pellet the precipitated proteins by centrifugation as
mentioned in the protocol.
-
29
DNA HYDRATION STEP
Re-hydration of samples is taking longer then expected.
There are two possibilities:
1. Mixing of sample was not done properly during the hydration
step.
Mix sample by gently tapping the sample tube to facilitate
dissolving of DNA.
2. The DNA pellets were overdried before adding Solution G4
(DNAHydration Solution).
Samples that are dried for longer than 1-2 hours at room
temperature or dried using a vacuum will need more time to
re-hydrate completely. IncubateDNA samples at 65°C for an hour
followed by incubation overnight at room temperature. Overnight
incubation at 65°C is not recommended.
DNA QUALITY
1. The size of the DNA purified is 50 kb or less.
a. Inappropriate storage of the starting material may degrade
DNA. Collect and store samples using methods that preserve DNA
integrity.
- Short term storage (5 days): store at -80°C
Alternatively, the samples can be stored in Solution G2 (Cell
Lysis Solution) at room temperature for extended periods of
time.
b. The MO BIO protocol involves steps that produce a negligible
amount of DNAshearing as compared to other traditional methods of
DNA extraction. TheProtein Precipitation Step, which involves
vortexing for 20 seconds, will not affect the size of the purified
DNA fragments.
2. A260/A280 ratios obtained are too high or too low.
Extremely low or high concentrations of DNA will not give good
A260/A280 ratios.For more accurate readings either concentrate by
ethanol precipitation or trydiluting your sample.The expected
A260/A280 ratios when using the UltraClean™Blood DNA Isolation kit
range from 1.8-2.0. DNA quality can also be deter-mined by
visualizing samples using agarose gel electrophoresis or
byperforming a restriction digest analysis. Further evaluation can
be done by performing PCR amplification using the DNA as a source
of template DNA.
-
30
DNA YIELD
The DNA yield obtained is too low.
1. The number of cells in the starting material was too low. It
is critical to use therecommended amount of cell material for a
particular protocol. Count the number of cells prior to the Cell
Lysis Step. In cases of insufficient numbers ofcells, the DNA
concentration will be lower during the DNA precipitation stepand
thus will reduce the DNA precipitation efficiency. A DNA carrier
such as0.5 µl Glycogen (20 mg/ml) per 300 µl Isopropanol can be
used to improve theefficiency of DNA precipitation if a low DNA
yield is expected or if workingwith a small number of cells (

2. Invert several times to mix and incubate at 4°C for 30
minutes.
3. Centrifuge samples according to the following table:
4. Drain the supernatant, add 70% Ethanol (shown in the table on
page 30) andinvert gently to wash the DNA.
5. Centrifuge at high speed as shown below.
6. Drain the supernatant and invert on a clean sheet of
absorbent paper to allow theDNA to air dry for 15-20 minutes.
7. Once the DNA is dry, add the appropriate volume of Solution
G4 (DNAHydration Solution) to the sample.
8. DNA can be stored short term at 4°C, but should be stored at
-20°C or -80°Cfor long term storage.
