Description

Description:
T4 Polynucleotide Kinase (PNK) catalyzes the transfer and exchange of the terminal gamma position phosphate of ATP to the 5′-hydroxyl terminus of double- and single-stranded DNA, RNA and nucleoside 3′-monophosphate molecules(1). T4 PNK also exhibits 3′-phosphatase and 2′,3’cyclic phosphodiesterase activities.(2-6)

Specific Activity: 133,333 U/mg

Applications:

  • End-labeling DNA or RNA for probes and DNA sequencing
  • Addition of 5′-phosphates to oligonucleotides to allow subsequent ligation
  • Removal of 3′-phosphoryl groups
