Description
Quick CIP is a heat-labile recombinant version of calf intestinal alkaline phosphatase (CIP) purified from a recombinant source. It can be heat inactivated at 80°C for 2 minutes. Quick CIP nonspecifically catalyzes the dephosphorylation of 5´and 3´ends of DNA and RNA phosphomonoesters. It also hydrolyses ribo- and deoxyribonucleoside triphosphates (NTPs and dNTPs). Quick CIP is useful in many applications that require the dephosphorylation of DNA or RNA ends. In cloning, dephosphorylation prevents re-ligation of linearized plasmid DNA. The enzyme can quickly dephosphorylate 5´protruding, 5´recessed, and blunt ends in just 10 minutes. Quick CIP may also be used to degrade unincorporated dNTPs in PCR reactions to prepare templates for DNA sequencing or SNP analysis
