The main advantages of SAP:
100% heat-inactivated at 65°C
Removes 5’-phosphates from DNA, RNA, dNTPs and proteins.
Works in restriction enzyme buffers.
Used in PCR clean-up.


Developed at ArcticZymes, first launched in 1993. Originates from the Arctic Shrimp (Pandalus borealis), from 2010 it has been produced as a recombinant version (rSAP). rSAP is better suited than native SAP (nSAP) for newer, more sensitive technologies.

Shrimp Alkaline Phosphatase (rSAP) has become one of today’s most-selling DNA modifying enzymes due to the added convenience through a complete heat inactivation. While most other alkaline phosphatases (from E. coli or Calf intestine) must be removed by extraction procedures, rSAP is completely inactivated after 15 minutes at 65°C. rSAP works well in common buffers without the requirement for other additions.
