Native T4-infected Escherichia coli Polynucleotide Kinase


Cat No.
NATE-0605
Description
Polynucleotide kinase catalyses a "forward reaction" transfer of the γ-phosphate of ATP to the 5' hydroxyl terminus of single-and double-stranded nucleic acids (DNA and RNA) and 3'-nucleoside monophosphates. In exchange reactions containing ADP, the enzyme will catalyze the exchange of 5'-terminal phosphate groups and ATP. The 3'-phosphatase activity enables the enzyme to remove 3'-phosphoryl groups from phosphorylpolynucleotides.

Alias
PNK; DNA kinase
Source
T4-infected Escherichia coli
Applications
Suitable for: • Sequencing or nucleic acid tagging (DNA and RNA) by 5′-end labeling • 5′ phosphorylation of oligonucleotides • Removal of 3′-phosphate groups from phosphorylpolynucleotides
