Specificity

Recognition sequence: 5′-G/TCGAC-3′
Cutting results: a 2-10-fold Sal I overdigestion of 1 μg λ DNA substrate results in 100% cutting
Heat inactivation: Inactivated at 65 °C for 15 minutes.

Application

SalI is a restriction endonuclease used for molecular biology methods to cleave DNA at the recognition sequence 5′-G/TCGAC-3′, generating fragments with 5′-cohesive ends.
