Specificity

Recognition sequence: 5′-GG/CC-3′
Ligation and recutting results: After 2-10-fold Hae III overdigestion of 1 μg λ DNA substrate, results in 100% cutting, >50% of fragments can be ligated, and >95% recut.
Heat inactivation: 80 °C for 20 minutes.

Application

HaeIII is a restriction enzyme that is used in molecular biology methods to cleave DNA at the recognition site 5′-GG/CC-3′ to generate DNA fragments with blunt termini.

Other Notes

Supplied with 10x Restriction Enzyme Buffer SM (B3158).
Comment: Inefficient for single-stranded DNA cleavage.
Hae III requires optimal reaction conditions in order to avoid star activity.
