Recombinant Human FCGR2A, His-tagged, Biotinylated

Specification :
| Description : This gene encodes one member of a family of immunoglobulin Fc receptor genes found on the surface of many immune response cells. The protein encoded by this gene is a cell surface receptor found on phagocytic cells such as macrophages and neutrophils, and is involved in the process of phagocytosis and clearing of immune complexes. Alternative splicing results in multiple transcript variants.? | 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 FcGR2A / CD32a, fused with 6×His tag at the C-terminus, has a calculated MW of 21.3 kDa. The predicted N-terminus is Gln 34. DTT-reduced Protein migrates as 29-32 kDa due to glycosylation. | Endotoxin : Less than 1.0 EU per μg of the Biotinylated FcGR2A / CD32a 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).
