Exonuclease I (20 U/µL) THERMO EN0581

Thermo Scientific Exonuclease I (ExoI) degrades single-stranded DNA in a 3'→5' direction. It releases deoxyribonucleoside 5'-monophosphates in a stepwise manner and leaves 5'-terminal dinucleotides intact.
It does not cleave DNA strands with terminal 3'-OH groups blocked by phosphoryl or acetyl groups.
• Active in PCR buffers
• Primer removal from PCR mixtures:
• prior to PCR product sequencing
• for one-tube "megaprimer" PCR mutagenesis
• Removal of single-stranded DNA containing a 3'-hydroxyl terminus from nucleic acid mixtures
• Assay for the presence of single-stranded DNA with a 3'-hydroxyl terminus
