> 95% by SDS-PAGE. The protein was observed as a single band migrating at molecular weight <10 kDa.

Supplied as
1.0mg/ml in Ammonium Acetate 50mM, pH 6.0. The concentration is calculated from the absorbance at 280nm (ε280=1280 M-1cm-1).

Under the above described conditions, to avoid precipitation or protein dimerization, the product can be concentrated up to 25mM.

-20°C. The protein is stable at 4°C for at least 2 weeks and at 25°C for at least several hours.
After initial defrost, aliquot product into individual tubes and refreeze at -20°C.
Avoid repeated freeze/defrost cycles.
NMR USE: after the experiments return the sample at 4°C.
