Recombinant Mouse S100b(Met1-Glu92) fused with His tag at C-terminal was expressed in E. coli.
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH7.4.
Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.
Greater than 95% as determined by reducing SDS-PAGE.
Lyophilized protein should be stored at < -20 centigrade, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7 centigrade for 2-7 days.Aliquots of reconstituted samples are stable at < -20 centigrade 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 100 μg/ml.Dissolve the lyophilized protein in ddH2O.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
The product is shipped at ambient temperature.
