BseC I (Cla I isoschizomer) Technical BrochureTechnical Brochure

BseCI is a restriction enzyme purified from Bacillus stearothermophilus.


Unit substrate: Lambda DNA.


Unit calculation assay conditions: 100 mM NaCl, 50 mM Tris-HCl  (pH 7.9 @ 25°C), 10  mM  MgCl2, 1 mM dithiothreitol, 100 μg/ml BSA. Incubate at 55oC.


Absence of contaminants: 150 units of BseCI do not produce any unspecific cleavage products after 16 hrs incubation with 1 μg of λ DNA at 55oC. After 100-fold overdigestion with BseCI greater than 95% of the DNA fragments can be ligated and recut with this enzyme.


Storage buffer: 100 mM KCl, 10 mM Tris-HCl (pH 7.9 @ 25°C), 0.1 mM EDTA, 1 mM dithiothreitol, 0.15% Triton X-100, 200 μg/ml BSA and 50% glycerol. Store at -20oC.


Heat inactivation: No.


Methylation Sensitivity:

dam methylation: Blocked by overlapping

dcm methylation: Not sensitive

CpG methylation: Blocked
