T4 DNA polymerase (5 U/μL) - 100 U

T4 DNA polymerase catalyzes the synthesis of DNA in the 5'-3' direction together with templates and primers. It can be used to catalyze the blunt ends of the 5' or 3' protruding ends of DNA, label DNA probe synthesis by a displacement reaction, synthesize the second chain during fixed-point mutation, and Clone PCR products without ligation reactions.
