T4 Polynucleotide Kinase (100u)

T4 Polynucleotide Kinase catalyzes the transfer of the γ-phosphate from ATP to the 5´-terminus of polynucleotides or to mononucleotides bearing a 5´-hydroxyl group. The enzyme, purified from recombinant E. coli, may be used to phosphorylate RNA, DNA and synthetic oligonucleotides prior to subsequent manipulations such as ligation.

Features - Benefits

• May Be Heat-Inactivated: T4 Polynucleotide Kinase may be inactivated by heating at 68°C for 10 minutes.
• Provided with 10X Reaction Buffer: 700mM Tris-HCl (pH 7.6 at 25°C), 100mM MgCl₂, 50mM DTT.
• Blue/White Cloning Qualified: Promega's blue/white cloning assay provides a higher level of quality control for enzymes used in cloning applications.
