Beschreibung

Application

HpaI is a restriction endonuclease that is used to cleave DNA at the recognition site 5′-GTT/AAC-3′, generating fragments with blunt ends.

Biochem/physiol Actions

Recognition sequence: 5′-GTT/AAC-3′
Ligation and recutting results: After 2-10-fold Hpa I overdigestion of 1 μg λ DNA substrate, results in 100% cutting, >80% of fragments can be ligated, and >95% recut.
Heat inactivation: Not completely inactivated at 65 °C for 15 minutes.

Physical form

Solution in 20 mM Tris-HCl, pH 7.5, 50 mM KCl, 0.5 mM EDTA, 5 mM 2-mercaptoethanol, 0.01% polydocanol, 50% glycerol (v/v) at 4°C

Other Notes

Supplied with 10x Restriction Enzyme Buffer SA (B7531).
