PvuII Technical BrochureTechnical Brochure
 PvuII is a restriction enzyme purified from a recombinant E.coli strain.

 

Unit substrate: Lambda DNA.

 

Unit calculation assay conditions: 50 mM NaCl, 10 mM Tris-HCl (pH 7.9 @ 25oC), 10 mM MgCl2, 1 mM dithiothreitol, 100 μg/ml bovine serum albumin and DNA. Incubate at 37oC.

 

Absence of contaminants: 100 units of Pvu II do not produce any unspecific cleavage products after 16 hrs incubation with 1 μg of Lambda DNA at 37oC. After 10-fold overdigestion with Pvu II 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: No.

 

Methylation Sensitivity:

dam methylation: Not sensitive

dcm methylation: Not sensitive

CpG methylation: Not sensitive

 

Star activity: Conditions of low ionic strength, high enzyme concentration, glycerol concentration >5% or pH >8.0 may result in star activity.
