|Source||E.coli strain that carries the cloned EcoR I gene from Escherichia coli|
|Assayed on||Lambda DNA|
|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.|
|Optimal SE-buffer||SE-buffer EcoRI (100 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 50 mM NaCl; 1 mM DTT.) + BSA|
|Enzyme activity (%)|
|50 - 75||75 - 100||75 - 100||75 - 100||50 - 75||50|
|Storage conditions||10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerolerol; Store at -20°C.|
|Ligations||After 40-fold overdigestion with enzyme about 95% 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 40 u.a. of enzyme for 16 hours at 37°C.
|Reagents Supplied with Enzyme||
10 X SE-buffer EcoRI, BSA (except E057m, E057T and E058T).|
For E057T and E058T an additional 10X SE-buffer ROSE is supplied.
|Methylation sensitivity||not tested|
|Inactivation 20 minutes under||65oC|
|Notes||High enzyme concentration and using of nonoptimal buffer may result 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.
