Diluent Buffer: 10mM Tris-HCl (pH 7.4 at 25°C), 100mM KCl, 1mM EDTA, 1mM DTT, 0.2mg/ml BSA and 50% glycerol.

Storage Buffer: 10mM Tris-HCl (pH 7.4 at 25°C), 100mM KCl, 1mM DTT, 1mM EDTA, 0.2mg/ml BSA and 50% glycerol.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 6 months at -20°C. 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.

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 37°C in 50ul of assay buffer.

Quality Control:
Overdigestion Assay: No detectable change in the specific fragmentation pattern is observed after 320-fold overdigestion (20u/ug lambda DNA x 16 hours) with VspI.

Ligation/Recutting Assay: After 50-fold overdigestion (3u/ug DNA x 17 hours) with VspI, more than 95% of the DNA fragments can be ligated at a 5'-termini concentration of 0.2uM. 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 10 units of restriction endonuclease for 4 hours.
