Technical BrochureTechnical Brochure

BshFI is a restriction enzyme purified from Bacillus sphaericus.


Unit substrate: Lambda DNA.


Unit calculation assay conditions: 50 mM potassium acetate, 20 mM Tris-acetate (pH 7.9 @ 25oC), 10 mM magnesium acetate, 1 mM dithiothreitol, 100 μg/ml bovine serum albumin and DNA. Incubate at 37oC.


Absence of contaminants: 200 units of BshF I do not produce any unspecific cleavage products after 16 hrs incubation with 1 μg of Lambda DNA at 37oC. After 50-fold overdigestion with BshF I, 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 bovine serum albumin and 50% glycerol. Store at -20oC.


Heat inactivation: 80oC for 20 minutes.


Methylation Sensitivity:

dam methylation: Not sensitive

dcm methylation: Not sensitive

CpG methylation: Not sensitive
