Pst I 来源于斯氏普罗威登斯菌

Recognition sequence: 5′-CTGCA/G-3′
Cutting results: a 2-10-fold Pst I overdigestion of 1 μg λ DNA substrate results in 100% cutting.
Heat inactivation: Inactivated at 80 °C for 20 minutes.

PstI is a restiction enzyme used in molecular biology applications to cleave DNA at the recognition sequence 5′-CTGCA/G-3′, generating DNA fragments with 3′- cohesive termini.

Supplied with 10x Restriction Enzyme Buffer SH (B3657).

Comment: Pst I requires optimal reaction conditions in order to avoid star activity.
