Description: Recombinant Human CD32a Protein is produced by mammalian expression system and the target gene encoding Ala36-Ile218 (His131Arg) is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4. Gene Symbol: FCGR2A Alternative 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; CD32Entrez Gene (Human): 2212SwissProt (Human): P12318Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : AAPPKAVLKL EPPWINVLQE DSVTLTCQGA RSPESDSIQW FHNGNLIPTH TQPSYRFKAN NNDSGEYTCQ TGQTSLSDPV HLTVLSEWLV LQTPHLEFQE GETIMLRCHS WKDKPLVKVT FFQNGKSQKF SHLDPTFSIP QANHSHSGDY HCTGNIGYTL FSSKPVTITV QVPSMGSSSP MGIHHHHHH 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 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.
