Purity > 95% by SDS-PAGE. The protein is observed, in denaturing conditions, as single band (monomer) migrating at a molecular weight below 14.4 kDa.
Supplied as 0.5 mg/mL solution in sodium acetate 50 mM pH 5.6. The concentration is calculated by the analysis of the absorbance at 280 nm (ε280= 6970 M-1cm-1 calculated).
Storage -20°C. The protein is stable at 4°C for at least 2 weeks and 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.
