Source: Bacillus stearothermophilus RFL1434

Concentration: 10u/ul

Unit Definition: One unit is defined as the amount of enzyme required to digest 1ug of lambda DNA in 1 hour at 55C in 50ul of assay buffer.

Dilution Buffer: 10mM Tris-HCl, pH 7.4 at RT, 100mM KCl, 1mM EDTA, 1mM DTT, 0.2mg/ml BSA, 50% glycerol.

Storage Buffer: 10mM Tris-HCl, pH 7.5 at RT, 50mM KCl, 1mM DTT, 0.1mM EDTA, 0.2mg/ml BSA, 50% glycerol.

Directions For Use: Incubate at 55C. (Incubation at 37C results in 10% activity.)

Supplied with:
R1625: Restriction Enzyme Buffer A, 10X. Suitable for use in Double Digest assays.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Enzyme Properties:
Thermal Inactivation: Enzyme is inactivated by incubation at 80C for 20min.

Stability during Prolonged Incubation: A minimum of 0.2units of enzyme is required for complete digestion of 1ug of lambda DNA in 16 hours at 55C

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 BseDI.

Ligation/Recutting Assay:
After 50-fold overdigestion (3u/ug DNA x 17 hours) with BseDI, more than 95% of the DNA fragments can be ligated at a 5'-termini concentration of 1uM. 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 restriction endonuclease for 4 hours.
