Bcl I Technical BrochureTechnical Brochure

BclI is a restriction enzyme purified from Bacillus caldolyticus.


Unit substrate: Lambda DNA (dam-).


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


Absence of contaminants: 100 units of BclI do no produce any unspecific clevage products after 16 hrs incubation with 1 μg of λ DNA (dam-) at 50°C. After 50-fold overdigestion with BclI, greater than 95% of the DNA fragments can be ligated and recut with this enzyme.



Storage buffer: 50 mM KCl, 10 mM Tris-HCl (pH. 7.4), 0.1 mM EDTA, 1 mM dithiothreitol, 200 μg/ml BSA, and 50% glycerol. Store at -20oC.



Heat inactivation: No.


Methylation Sensitivity:

dam methylation: Blocked

dcm methylation: Not sensitive

CpG methylation: Not sensitive
