Storage and StabilityAliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Enzyme Properties
Methylation Effect
Blocked by CpG methylation.
Dam, Dcm, EcoKl, EcoBlNeber overlaps, no effect
Stability during Prolonged Incubation
A minimum of 0.1units of B2922 is required for complete digestion of 1ug of lambda DNA in 16 hours at 37°C.
Thermal Inactivation
B2922 is inactivated by incubation at 65°C for 20min.
Quality Control
Overdigestion Assay
No detectable change in the specific fragmentation pattern is observed after 160-fold overdigestion (10u/ug lambda DNA x 16 hours) with Bsh1236I.
Ligation/Recutting Assay
After 50-fold overdigestion (3u/ug DNA x 17 hours) with Bsh1236I, more than 95% of the DNA fragments can be ligated at a 5'-termini concentration of 1.6uM. More than 95% of these can be recut.
Labeled Oligonucleotide (LO) Assay
No detectable degradation of a single-stranded and double-stranded labeled oligonucleotide was observed after incubation with 10units of B2922 for 4 hours.
