Human Fc gamma RIIB/CD32b Protein
Recombinant Human Fc gamma RIIB/CD32b Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Ala46-Pro217 [Accession | P31994-1].
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.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-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.
Human Fc gamma RIIB on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Human Fc gamma RIIB is greater than 95% as determined by SEC-HPLC.
Rituximab captured on CM5 Chip via Protein A can bind Human Fc gamma RIIB, His Tag with an affinity constant of 3.46 μM as determined in SPR assay (Biacore T200).
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.
