原厂资料：

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.

Features - Benefits

• Available at High Concentration: Cat.# M2825 contains 1,000 units of CIAP at 20u/μl.
• Blue/White Cloning Qualified: Promega's blue/white cloning assay provides a higher level of quality control for enzymes used in cloning applications.
• Provided with 10X Reaction Buffer: 0.5M Tris-HCl (pH 9.3 at 25°C), 10mM MgCl2, 1mM ZnCl2, 10mM spermidine.

Applications

• Preventing religation of linearized cloning vehicle DNA by removing phosphate groups from both 5´ termini.
• Removing 5´ phosphate groups prior to end-labeling with T4 Polynucleotide Kinase.
