Product Description	Recombinant Human Fc gamma RIIB/C (CD32b/c) Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Ala46-Pro217.
Product Background	The Fc gamma Rs have been divided into three classes based on close relationships in their extracellular domains; these groups are designated Fc gamma RI (also known as CD64), Fc gamma RII (CD32), and Fc gamma RIII (CD16). Each group may be encoded by multiple genes and exist in different isoforms depending on species and cell type.
Product Category	Recombinant Protein / Antibody discovery / Fc receptors

Protein	Fc gamma RIIB/C (CD32b/c)
Synonyms	Fc gamma RII; Fc gamma RIIB; Fc gamma RIIC; CD32; CD32b; CD32c; CDw32; FCG2; IGFR2; CD32A; FCG2 ; FcGR; FCGR2; FCGR21; FCGR2A; FcγRIIB; Fc γRIIB; Fcγ RIIB; Fc γ RIIB
Accession	P31994-1

Amino Acid Range	Ala46-Pro217
Molecular Weight	The protein has a predicted MW of 22.5 kDa. Due to glycosylation, the protein migrates to 32-37 kDa based on Bis-Tris PAGE result.
Activity	The affinity constant of 16.72 uM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-His-Avi
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 0.01 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
