Application

BclI is a restriction endonuclease used in molecular biology applications to cut DNA at the recognition sequence 5′-T/GATCA-3′, resulting in fragments with 5′-cohesive termini.

Biochem/physiol Actions

Recognition sequence: 5′-T/GATCA-3′
Cutting results: a 2-10-fold Bcl I overdigestion of 1 μg λ DNA substrate results in 100% cutting.
Heat inactivation: This enzyme cannot be heat inactivated at 65 °C for 15 minutes.

Physical form

Solution in 20 mM Tris-HCl, pH 8.0, 0.1 mM EDTA, 200 mM NaCl, 10 mM 2-Mercaptoethanol, 0.2 % Triton X-100 (v/v), 50% glycerol (v/v) at 4°C

Other Notes

Cleavage activity: Bcl I will only partially cleave DNA isolated from E. coli strains that have the dam methylase (dam+ strains).
Comment: Bcl I is optimally active at 50°C.
Supplied with 10x Restriction Enzyme Buffer SM (B3158).
