Purity
> 95% by SDS-PAGE. The protein is observed, in denaturing conditions, as a single band migrating between 35.0 and 45.0 kDa.

Supplied as
1.0 mg/mL solution in phosphate buffer 20 mM pH 7.2, EDTA 0.1 mM, NaN3 3 mM, Maltotriose 3 mM, Pefabloc® (AEBSF) 50 uM. The concentration is calculated by the analysis of the absorbance at 280 nm (ε280 = 66350 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 1.5 mM.

Storage
-20°C. The protein is stable at 4°C for months.
Avoid repeated freeze/thaw cycles.
