biotechrabbit™ GenUP Exo SAP Kit is designed for quickly and easily cleaning up PCR amplification reactions, enabling their direct use in sequencing or genotyping.
The kit provides a combination of Shrimp Alkaline Phosphatase (SAP) and Exonuclease 1 (ExoI) for removing nucleotides and primers. Double-stranded DNA is not affected, ensuring 100% recovery of PCR products.
Both enzymes are active in PCR buffers and completely inactivated by heating at 80°C: no further processing is required. Shrimp Alkaline Phosphatase dephosphorylates nucleotides and primers, and the 3' → 5' exonuclease activity of Exonuclease 1 degrades single-stranded primers.
