BstX2 I

Description

Recognition site and hydrolysis position:

Source: An E.coli strain that carries the cloned BstX2I gene from Bacillus stearothermophilus X2
Unit definition:
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 60°C in a total reaction volume of 50 μl.
Assayed on:
Lambda DNA
Optimal SE-buffer: SE-buffer G
Enzyme activity (%):

Storage conditions: 10 mM Tris-HCl (pH 7.6); 100 mM NaCl; 0.1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
