Kpn I

Enzyme name Kpn I
Prototype KpnI
SKU SE-E079
Turbo version Available
High-concentration version Available
Recognition site
5'… GGTAC▼C …3'
3'… C▲CATGG …5'
Source An E.coli strain that carries the cloned Kpn I gene from Klebsiella pneumonia
Optimal buffer SE-buffer B
Optimal temperature 37 °C
Inactivation temperature 80 °C
Buffer activity
BGOWYROSE
1002525257550
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); 50 mM NaCl; 0,1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
Ligation After 20-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 20 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity Not blocked by overlapping Dcm methylation (C m CWGG) GGTA CC WGG
Supplied with enzyme 10 X SE-buffer B, BSA
Notes High enzyme concentration may result in star activity. Long incubation with BSA is not recommended due to star activity. To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml.
