Description：Recombinant Human S100A9 Protein is produced by E. coli expression system and the target gene encoding Thr2-Pro114 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4.Gene Symbol：S100A9Alternative Names：CAGB; CFAG; MRP14; Protein S100-A9; Calgranulin-B; Calprotectin L1H subunit; Leukocyte L1 complex heavy chain; Migration inhibitory factor-related protein 14; MRP-14; p14; S100 calcium-binding protein A9 Entrez Gene (Human)： 6280; SwissProt (Human)： P06702; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：TCKMSQLERN IETIINTFHQ YSVKLGHPDT LNQGEFKELV RKDLQNFLKK ENKNEKVIEH IMEDLDTNAD KQLSFEEFIM LMARLTWASH EKMHEGDEGP GHHHKPGLGE GTPDirections 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 1X PBS. 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.
