Alkaline Phosphatase, Calf Intestinal (CIAP)

Alkaline Phosphatase, Calf Intestinal (CIAP), catalyzes the hydrolysis of 5´-phosphate groups from DNA, RNA, and ribo- and deoxyribonucleoside triphosphates. This enzyme is used to prevent recircularization and religation of linearized cloning vector DNA by removing phosphate groups from both 5´-termini and may also be used for the dephosphorylation of 5´ phosphorylated ends of DNA or RNA for subsequent labeling with [32P]ATP and T4 Polynucleotide Kinase. CIAP is active on 5´ overhangs, 5´ recessed and blunt ends.
