Product Introduction
Exonuclease VII, derived from E. coli, cuts single-stranded DNA in the 5′ 3′ and 3′ 5′ directions and has no activity against linear or circular double-stranded DNA. When PCR is complete, the oligonucleotide primer can be removed using exonuclease VII, and then the next PCR can be performed using a different primer. Exonuclease VII digesting single-stranded DNA does not require metal ions. This product is a high purity protein obtained by recombinant expression of exonuclease VII genes (XseA and XseB).
Application
1. Remove excess primers after PCR
2. The oligonucleotide primer was removed after PCR
3. Remove single-stranded DNA from double-stranded DNA.
