Recombinant Bacteriophage Lambda Exonuclease

Cat.No.: xis-56B
Product Overview: Purified from a strain of E. coli that overexpresses the exonuclease gene from bacteriophage Lambda.
Description: Lambda Exonuclease is a highly processive 5′→3′ double-stranded exonuclease that degrades one strand of the duplex. Lambda exonuclease can initiate at blunt DNA or DNA containing 3′ single-stranded overhangs. Lambda Exonuclease has greatly reduced activity on non-phosphorylated DNA, single-stranded DNA and DNA having protruding 5′ single-stranded termini. Lambda exonuclease will not initiate at a nick or gap.
Source: E. coli
