Purity
> 95% by SDS-PAGE. The protein is observed, in denaturing conditions, as a single band migrating at a molecular weight between 14.4 and 18.4 kDa.

Supplied as
0.2 mg/mL solution in Tris 20 mM, pH 7.2, CaCl2 10 mM, ZnCl2 0.1 mM, NaCl 0.3 M, acetohydroxamic acid (AHA) 0.2 M. The concentration is calculated by the analysis of the absorbance at 280 nm (ε280= 28420 M-1cm-1 calculated).

Storage
-80°C. After initial defrost, aliquot the product into individual tubes and refreeze at -80°C.
Avoid repeated freeze/thaw cycles.
