Description：Recombinant Human S100-B Protein is produced by E.coli expression system and the target gene encoding Met1-Glu92 is expressed with a 6His tag at the N-terminus.Form：Lyophilized from a 0.2 μm filtered solution of 20mM PBS, 150mM NaCl, pH7.4.Gene Symbol：S100BAlternative Names：Protein S100-B; S-100 protein beta chain; S-100 protein subunit beta; S100 calcium-binding protein B Entrez Gene (Human)： 6285; SwissProt (Human)： P04271; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MNHKVHHHHH HMSELEKAMV ALIDVFHQYS GREGDKHKLK KSELKELINN ELSHFLEEIK EQEVVDKVME TLDNDGDGEC DFQEFMAFVA MVTTACHEFF EHECDirections for Use：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.Quality Control：Endotoxin: Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. 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.
