EcoR V

Description

Recognition site and hydrolysis position:

Source: An E.coli strain, that carries the cloned gene EcoRV from Escherichia coli
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
Optimal SE-buffer: SE-buffer W
Enzyme activity (%):

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.
Ligations:
After 20-fold overdigestion with enzyme 90% of the DNA fragments can be ligated and recut.
Non-specific hydrolisis:
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 20 u.a. of enzyme fro 16 hours at 37°C. Reagents Supplied with Enzyme 10 X SE-buffer W, BSA
Reagents Supplied with Enzyme:
Methylation sensitivity: not tested
Notes: High enzyme concentration results in star activity.
Do not use BSA for long incubation
To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml.
