Molecular Weight Separation Range for Proteins BioSep-SEC-S
1 Based on a GuaranteedAlternative to the Column You Currently Use
How well one protein of interest is separated from another is related to the efficiency of a column; the higher the efficiency the greater the baseline separation between the analytes. As shown in the chart below, BioSep has a very high efficiency, thus making it an excellent column for protein separations via gel filtration/size exclusion.

Proteins on BioSep-SEC-S3000
“I have been using the BioSep 3000 size exclusion columns for the past five years to purify radioiodinated antibodies. These columns have provided us with consistent, reproducible results for a very reasonable and competitive price. In addition, the customer service and technical support provided by Phenomenex is unlike that of any other vendor that I deal with and is truly commendable and a selling point in itself. I would highly recommend this column.Pam Zaller-Farrington - SolidPhase Inc. ’’

Characterizing and purifying a protein of interest shouldn’t be a complicated, time consuming task. However, when results aren’t reproducible, sample loading is limited, and yields are low, that is exactly what it becomes. BioSep can simplify work and reduce time in the lab with its benefits and advantages outlined below.
“ I have used the BioSep-SEC-S2000 column and have found that it gives good, reproducible profiles of carbohydrate polymers. We use the column as part of a GLP release testing method and require its reproducibility to validate our methods.’’ Anthony Piotrkowski, Gilatech Inc.
Rs-1 is the resolution between IgM and IgA. Rs-2 is the resolution between IgA and IgG. Rs-3 is the resolution between IgG and the void volume. As seen in the figure to the right, the resolution between the peaks of interest remain around 1.5, the ideal resolution value, from 2.0 mg up to 16.0 mg.
Large Loading Capacity
Ensure resolution of critical components regardless of sample loading
Excellent choice for prep or process scale separations
Within protein folding and activity constraints, column capacity can be further increased with the use of small percentages of organic solvent or with an increase in column temperature

Reproducibility Guaranteed
Each batch of silica-based material is carefully monitored to ensure that particles have the proper size, shape, and pore characteristics batch-to-batch
Every column is performance tested to ensure the same high quality separation column-to-column

“ I have been using the BioSep-SEC-3000 column with the BioSep guard column to estimate the percentage of monomeric form of BSA and IgG for more than three years.
Over the last 12 months I critically evaluated the performance of the column using Life Technologies BSA, Sigma amylase. The variation in the retention times of both proteins between runs over the period examined was only 5 %. The mean pressure varied within 10 % between runs. I have enough confidence in the BioSep column that I continue to
use this column for the QC tests in our laboratory. I fully recommend the BioSep-SEC-3000.Minh Lengoc, Life Technologies Ltd., New Zealand ’’
High Sample Yields and Recovery of Biological Activity
Hydrophilically bonded silica gel has low adsorption of proteins resulting in higher yields
Relatively little surface activity due to free silanols limits interaction of protein with base silica
Lysozyme is a somewhat hydrophobic and very basic protein (pKa 11.0) which can be used as a probe to test the surface activity of SEC columns. This figure shows only nominal changes in the value of KD for this enzyme when pH was changed.
3
The KD values were calculated using the formula: KD = (Ve-Vo )/(VT-Vo )
Where Ve is the elution volume of the sample, VT and Vo are the total liquid volume and void volumes of the columns, respectively.

Separating a protein mixture of molecular weights from 872 to 300,000 daltons illustrates the wide range that can be easily separated on BioSep-SEC-S2000. An excellent linear correlation of 0.994 is obtained for the log MW vs KD plot. Interpolation of unknown protein is easier and more accurate when the separation is efficient and linear.

BioSep™-SEC-S Column Options
The BioSep product line offers 3 different phase options to fit the appropriate exclusion range of your sample mixture. All three phases have a narrow pore size distribution, which produces exceptional separations required for high performance gel filtration/size exclusion. Depending on your analysis needs, BioSep 2000, 3000, and 4000 are all available in PEEK hardware and in narrow bore, analyti-cal, and preparative dimensions.

Proteins on BioSep-SEC-S3000
Mixtures of proteins were subjected to size-exclusion chromatography on BioSep-SEC-S3000. Two mg each of the proteins were dissolved in 0.5 mL of the mobile phase buffer, 50 mM NaH2PO4, pH 6.8. Then 20 µL was injected onto the column. The plot of log MW vs. KD was obtained from runs of three different protein mixtures (r2 = 0.977).
