back to the Office of Biotechnology when finished.

DNA Fingerprinting

Preparation of the Student Materials

• The supplies can best be provided to the class in groups of five students.

• The DNA samples should be refrigerated until class time.• It is too expensive for the Office of Biotechnology to

provide DNA for every student in a class. The office will provide enough DNA, restriction endonuclease, and reaction buffer for a minimum of two groups of five students or a maximum of one group of five students in every class section, whichever is greater.

DNA Fingerprinting Preparation of the Student Materials

(cont.)

• For the other student groups, use distilled water to replace the DNA, restriction endonuclease, and reaction buffer.

• Every group of students should be provided with the blue migration dye.

DNA and Enzyme

Lab Preparation

DNA and Enzyme PrepStep 1

• For each group of students label 7-1.5 ml tubes "C,1,2,3,4, N and D" with a permanent felt pen.

• Tube "N" will contain the enzyme mixture.

• Tube "D" will contain the migration dye.

DNA Fingerprinting

DNA and Enzyme PrepStep 2

• Pipette 17 µl of a 0.025 µg/µl concentration of pBR322 DNA into the tube labeled "C."

DNA Fingerprinting

DNA and Enzyme PrepStep 3

• In the tube labeled "1" pipette 17 µl of 0.15 µg/µl concentration of lambda DNA.

DNA Fingerprinting

DNA and Enzyme PrepStep 4

• In the tube labeled "2" pipette 17 µl of 0.075 µg/µl concentration of Ad-2 DNA.

DNA Fingerprinting

DNA and Enzyme PrepStep 5

• In the tube labeled "3" pipette 17 µl of 0.025 mg/ml concentration of pBR322 DNA.

DNA Fingerprinting

DNA and Enzyme PrepStep 6

• In the tube labeled "4" pipette 17 µl of 0.025 µg/µl concentration of pUC19 DNA.

DNA Fingerprinting

DNA and Enzyme PrepStep 7

• In the microcentrifuge tube (1.5 ml) labeled "N," pipette 15 µl of reaction buffer and 3 µl Bgl 1.

DNA Fingerprinting

DNA and Enzyme PrepStep 8

• In a microcentrifuge tube (1.5 ml) labeled "D," pipette 40 µl of blue migration dye.
