1.DIGESTION PROTOCOL -Procedure Keep all enzymes and buffers used on ice. Add 500ng of DNA to the appropriately labelled tube. Add distilled water to the tubes for a total volume of 40ul in each tube. Pipet 5ul of NEB Buffer 2 to each tube. Calculation example (with 50ng/ul as DNA sample concentration): 500ng ÷ 50ng/ul = 10ul of DNA sample 50ul (total volume) – 10ul (DNA sample) = 40ul of distilled water Pipet 5ul of NEB Buffer 2 to each tube. Pipet 0.5ul of BSA to each tube. Add 1ul enzyme 1 Add 1ul enzyme 2 The total volume in each tube should be approximately 50ul. Mix well by pipetting slowly up and down. Incubate the restriction digests at 37°C for 35 minutes, then 80°C for 20 minutes.
-Procedure
Pipet 5ul of NEB Buffer 2 to each tube. Calculation example (with 50ng/ul as DNA sample concentration):
500ng ÷ 50ng/ul = 10ul of DNA sample
50ul (total volume) – 10ul (DNA sample) = 40ul of distilled water
