Description：Recombinant Human FCAR Protein is produced by Mammalian expression system and the target gene encoding Gln22-Asn227 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：FCARAlternative Names：CD89; Immunoglobulin alpha Fc receptor; IgA Fc receptor; CD89 Entrez Gene (Human)： 2204; SwissProt (Human)： P24071; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：QEGDFPMPFI SAKSSPVIPL DGSVKIQCQA IREAYLTQLM IIKNSTYREI GRRLKFWNET DPEFVIDHMD ANKAGRYQCQ YRIGHYRFRY SDTLELVVTG LYGKPFLSAD RGLVLMPGEN ISLTCSSAHI PFDRFSLAKE GELSLPQHQS GEHPANFSLG PVDLNVSGIY RCYGWYNRSP YLWSFPSNAL ELVVTDSIHQ DYTTQNVDHH HHHHDirections 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.
