Description：Recombinant Human FCGR2A Protein is produced by mammalian expression system and the target gene encoding Ala36-Ile218 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 7.4.Gene Symbol：FCGR2AAlternative Names：CD32; FCG2; FCGR2A1; IGFR2; Low affinity immunoglobulin gamma Fc region receptor II-a; IgG Fc receptor II-a; CDw32; Fc-gamma RII-a; Fc-gamma-RIIa; FcRII-a; CD32 Entrez Gene (Human)： 2212; SwissProt (Human)： P12318; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：APPKAVLKLE PPWINVLQED SVTLTCQGAR SPESDSIQWF HNGNLIPTHT QPSYRFKANN NDSGEYTCQT GQTSLSDPVH LTVLSEWLVL QTPHLEFQEG ETIMLRCHSW KDKPLVKVTF FQNGKSQKFS RLDPTFSIPQ ANHSHSGDYH CTGNIGYTLF SSKPVTITVQ VPSMGSSSPM GIIVDHHHHH HDirections 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.
