Supplier: New England Biolabs, Inc. M0379S
Exonuclease VII, (Exo VII) derived from E. coli, cleaves single-stranded DNA (ssDNA) from both 5' to 3' and 3' to 5' direction. This enzyme is not active on linear or circular dsDNA. It is useful for removal of single stranded oligonucleotide primers from a completed PCR reaction when different primers are required for subsequent PCR reactions. Digestion of ssDNA by Exonuclease VII is metal-independent.
