Ambient

A low-affinity activating IgG receptor, CD32a (FcgammaRIIa) carries a 167R (arginine) polymorphism that alters immune-complex engagement relative to the 167H allele. This biotinylated recombinant human CD32a (167R) protein, produced in HEK293 cells, is designed for streptavidin-based capture in SPR, BLI, and ELISA workflows and is a protein reagent rather than an antibody. Prepared to in vivo-grade, ultra-low-endotoxin specifications, it is offered in scalable milligram to gram quantities for bulk and high-throughput laboratories. The biotin tag makes it ideal for immobilized binding and kinetic studies of allele-specific Fc-receptor interactions, supplied strictly for research use only.

The sequence of the extracellular domain of human CD32a (Ala 36-Ile 218) was fused with a C-terminal tag consisting of the AVI tag, TEV protease recognition sequence and a 10-His tag.

Lyophilized from sterile PBS, pH 7.4. No preservatives or cryoprotectants have been added. To obtain a final concentration of 1 mg/ml reconstitute 0.25 mg vials with 0.25 ml water and 1.0 mg vials with 1.0 ml water.

Lyophilized proteins are stable at ambient temperature for at least 2 weeks. If the protein is not to be used immediately then the protein should be stored in lyophilized form at -20 °C for up 12 months. Once the protein has been reconstituted we recommen
