    Purification
    
    > 95% by SDS-PAGE. The protein is observed, in denaturing conditions, as a single band migrating at molecular weight below 14.4 kDa.
    
    Formulation
    
    1.0 mg/mL solution in ammonium acetate 50 mM pH 6.0. The concentration is calculated by the analysis of the absorbance at 280 nm (ε280 = 1280 M^-1cm^-1 calculated).
    (Unless otherwise specified, NMR tubes will be sold at a concentration of 1mM)
    
    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.
    NMR USE: after the experiments return the sample at 4°C.
