BssNA I

Enzyme name BssNA I
Prototype SnaI
SKU SE-E261
Turbo version Not available
High-concentration version Not available
Recognition site
5'… GTA▼TAC …3'
3'… CAT▲ATG …5'
Source Bacillus stearothermophilus NA
Optimal buffer SE-buffer W + BSA
Optimal temperature 37 °C
Inactivation temperature не инактивируется
Buffer activity
BGOWYROSE
50507510075100
Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on Lambda DNA
Storage conditions 10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 100 μg/ml BSA; 50% glycerol; Store at -20°C.
Ligation After 10-fold overdigestion with enzyme more than 90% of DNA fragments can be ligated and recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity not tested
Supplied with enzyme 10 X SE-buffer W, BSA
Notes High enzyme concentration may result in star activity To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation.
