Exonuclease I（Exo I）

This product is derived from recombinant E.coli strain, carrying the Exo I gene, with exonuclease activity of hydrolyzing single-stranded DNA from the 3'-5' direction, which can gradually release deoxyribonucleic acid 5 'monophosphate and leave a complete 5' end dinucleotide. This product is mainly used to degrade digestion primers after PCR amplification, and has no activity for double-stranded DNA and 3 'OH terminal DNA strands closed by phosphoryl or acetyl groups
