Recombinant Human FCGR3B, His-tagged, Biotinylated

Specification :
| Description : The protein encoded by this gene is a low affinity receptor for the Fc region of gamma immunoglobulins (IgG). The encoded protein acts as a monomer and can bind either monomeric or aggregated IgG. This gene may function to capture immune complexes in the peripheral circulation. Several transcript variants encoding different isoforms have been found for this gene. A highly-similar gene encoding a related protein is also found on chromosome 1. | Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Trehalose are added as protectants before lyophilization. | Molecular Mass : Biotinylated FCGR3B / CD16b, fused with 6×His tag at the C-terminus, has a calculated MW of 21.7 kDa. The predicted N-terminus is Gly 17. DTT-reduced Protein migrates as 38-50 kDa due to glycosylation. | Endotoxin : Less than 1.0 EU per μg of the Biotinylated FCGR3B / CD16b by the LAL method. | Purity : >95% as determined by reduced SDS-PAGE. | Storage : Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4°C); After reconstitution under sterile conditions for 3 months (-70°C).
