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

Supplied as
1 mg/mL solution in phosphate buffer 50 mM pH 7, NaN3 0.02%. The concentration is calculated by the analysis of the absorbance at 280 nm (ε280 = 1490 M-1cm-1 calculated).
(unless otherwise specified, NMR tubes will be sold at a concentration of 1mM)

Characteristics
Under the above described conditions, to avoid precipitation or protein dimerization, the product can be concentrated up to 2mM.

Storage
-20°C. The protein is stable at 4°C for months. Avoid repeated freeze/thaw cycles.
NMR USE: after the experiments return the sample at 4°C.
