Lyophilized from a 0.2 μm filtered solution of 20mM PB，150 mM NaCl，3% Trehalose，0.02% Tween 80，4% Mannitol，pH 7.4.

Lyophilized

The product is shipped at ambient temperature.Upon receipt, store it immediately at the temperature listed below.

Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.

Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100μg/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
