Available mutants
WT – CAT # G02CLM01

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
1.0 mg/mL solution in Tris 20 mM pH 8.0, NaCl 150 mM, CaCl₂ 2 mM, Complete Protease Inhibitor Cocktail EDTA-free (Roche). The concentration is calculated by the analysis of the absorbance at 280 nm (ε₂₈₀= 2980 M^-1cm^-1 calculated). It is strongly recommended to add 1 tablet of Complete Protease Inhibitor Cocktail EDTA-free (Roche) in 1000 mL of buffer in case of buffer exchange.

Storage
-20°C. The protein is stable at 25°C for several hours. After initial defrost, aliquot the product into individual tubes and refreeze at -20°C.
Avoid repeated freeze/thaw cycles.
