Shrimp Alkaline Phosphatase (SAP)

Shrimp Alkaline Phosphatase (SAP) nonspecifically catalyzes the dephosphorylation of 5'-termini DNA and RNA phosphomonoesters but does not degrade diphosphate or triphosphate linkages. The enzyme acts on 5' protruding, recessive and blunt 5'-termini. Unlike Calf Intestinal Alkaline Phosphatase, SAP is irreversibly heat inactivated at 65°C for 15 minutes, allowing for streamlining of cloning experiments.
