T4 polynucleotide kinase mechanism
WebIf your insert is a PCR product, it will not have 5'-phosphates unless specified during primer synthesis or added by T4 polynucleotide kinase. For optimal cloning results, we recommend ligating a phosphorylated PCR product to a dephosphorylated vector to minimize self ligation of vector and reduce background colonies.

WebT4 Polynucleotide Kinase (T4 PNK) catalyzes the transfer of the γ-phosphate from ATP to the 5’-OH group of single- and double-stranded DNAs and RNAs, oligonucleotides or nucleoside 3’-monophosphates (forward reaction). The reaction is reversible. In the presence of ADP T4 Polynucleotide Kinase exhibits WebThe “kinase” reaction uses T4 polynucleotide kinase (T4 kinase) to transfer labeled phosphate to the 5′ end of the DNA molecule ( 6) Fig. 1B. This method is ideal for labeling oligonucleotides, which are normally synthesized without a 5′ phosphate.
