Abstract
Exonuclease VII efficiently cleaves single-stranded DNA (ssDNA) from both 5´→3´ and 3´→5´ direction. This enzyme is not active on linear or circular dsDNA

Safety warnings
Please see SDS (Safety Data Sheet) for hazards and safety warnings.
Set-up the reaction as follows:
COMPONENTSReaction Volumes
 PCR Product5 μl
 Exonuclease VII 2 μl (20 units)
Pipetting
Incubate the mix at Temperature37 °C for Duration00:30:00 .
Incubation
Heat inactivate Temperature95 °C for Duration00:10:00 prior to Sanger DNA sequencing.
For other downstream molecular cloning applications column cleanup is recommended.
Note
Note: See Exo-CIP™ Rapid PCR Cleanup Kit (NEB #E1050) for Sanger Sequencing, SNP detection, or library preparation for NGS.

To clean up treated samples, we recommend using one of the following steps:

a. Column clean up (we recommend the Monarch® PCR & DNA Cleanup Kit, NEB #T1030), or

b. Running the reaction on an agarose gel, and then extracting the DNA (we recommend the Monarch Gel Extraction Kit, NEB #T1020), or

c. Performing a phenol/chloroform extraction followed by ethanol precipitation.
