Calf Intestinal Alkaline Phosphatase (CIAP) is a phosphomonoesterase that removes 3´ and 5´ phosphates from DNA and RNA.
Concentration: 20 units/μL
Applications: Dephosphorylation of 5´-phosphorylated termini of vector DNA to prevent self-ligation (1). Dephosphorylation of 5´ termini of nucleic acids prior to forward reaction with kinase.
Source: Purified from calf intestinal mucosa.
Performance and Quality Testing: Endodeoxyribonuclease, 3´ exodeoxyribonuclease, and ribonuclease assays; dephosphorylation efficiency measured in a transformation assay.
Unit Definition: One unit hydrolyzes 1 μmol of 4-nitrophenyl phosphate in 1 min. at 37°C.
Unit Reaction Conditions: 1 M diethanolamine buffer, 10 mM 4-nitrophenyl phosphate, 0.25 mM MgCl2 (pH 9.8) in 900 μl for 10 min. at 37°C.
