Description: Recombinant Human FCGR2B Protein is produced by Mammalian expression system and the target gene encoding Thr43-Pro217 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.2. Gene Symbol: FCGR2B Alternative Names: CD32; FCG2; IGFR2; Low affinity immunoglobulin gamma Fc region receptor II-b; IgG Fc receptor II-b; CDw32; Fc-gamma RII-b; Fc-gamma-RIIb; FcRII-b; CD32Entrez Gene (Human): 2213SwissProt (Human): P31994Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : TPAAPPKAVL KLEPQWINVL QEDSVTLTCR GTHSPESDSI QWFHNGNLIP THTQPSYRFK ANNNDSGEYT CQTGQTSLSD PVHLTVLSEW LVLQTPHLEF QEGETIVLRC HSWKDKPLVK VTFFQNGKSK KFSRSDPNFS IPQANHSHSG DYHCTGNIGY TLYSSKPVTI TVQAPVDHHH HHH Directions 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.
