T4 Polynucleotide Kinase catalyzes the transfer and exchange of gamma-phosphate of ATP to the 5´-hydroxyl terminus of polynucleotides (double-and single-stranded DNA and RNA) and nucleoside 3´-monophosphates.
Purified from a strain of E. coli that carries a T4 Polynucleotide Kinase expression plasmid.
Heat inactivation: 70°C for 15 minutes.
Enzyme and buffer should be stored at -20°C. Enzyme is stable for 12 months if handled properly.
