INTRODUCTION
This stage achieves four goals: polishing the ends of double-stranded DNA, ligation of synthetic linkers or adaptors, digestion of the attached linkers to create cohesive termini, and preparing the cDNA for cloning.
MATERIALS
5x Bacteriophage T4 DNA polymerase repair buffer
ATP (10 mM)
Omit ATP from the ligation reaction in Step 2 if the ligation buffer contains ATP.
Bacteriophage T4 DNA ligase
Bacteriophage T4 DNA polymerase
Do not use the Klenow fragment of E. coli DNA polymerase.
Bromophenol blue (0.25% w/v in 50% glycerol)
Control DNA
Please see note to Step 10.
EDTA (0.5 M, pH 8.0)
Ethanol
Optional, please see
