Fc gamma RIIA/CD32a Antibody (8.7) [CoraFluor™ 1]

CoraFluor™ 1, amine reactive (Catalog:7920) and CoraFluor™ 2, amine reactive (Catalog # 7950) are terbium-based probes that have been developed for use as TR-FRET donors. They emit wavelengths compatible with commonly used fluorescent acceptor dyes such as BODIPY® (or BDY) and Janelia Fluor® dyes, FITC (Catalog # 5440), TMR and Cyanine 5 (Catalog # 5436). CoraFluor™ fluorescence is brighter and more stable in biological media than existing TR-FRET donors, leading to enhanced sensitivity and improved data generation. CoraFluor™ 1 exhibits excitation upon exposure to a 337 nm UV laser.

• Reactivity: Hu
• Applications: Flow, ICC/IF, CyTOF-ready, ICC/IF
• Clone: 8.7

Fc gamma RIIA/CD32a Antibody (8.7) [CoraFluor™ 1] Summary

• Description: CoraFluor(TM) 1 is a high performance terbium-based TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) or TRF (Time-Resolved Fluorescence) donor for high throughput assay development. CoraFluor(TM) 1 absorbs UV light at approximately 340 nm, and emits at approximately 490 nm, 545 nm, 585 nm and 620 nm. It is compatible with common acceptor dyes that absorb at the emission wavelengths of CoraFluor(TM) 1. CoraFluor(TM) 1 can be used for the development of robust and scalable TR-FRET binding assays such as target engagement, ternary complex, protein-protein interaction and protein quantification assays.

• Immunogen: K562 and FcgRII+L cells
• Localization: Cell Surface
• Specificity: This monoclonal antibody reacts with a CD32 (FcgRII) epitope distinct from that defined by monoclonal antibody 8.26 and the epitope overlaps with that of monoclonal antibody 7.30 (cluster 4). It displays a stronger reaction with Daudi than with U937 cells. The epitope is located in domain 2 of FcgRIIa. Its Fab'2 fragments block immune complex binding. CD32 (FcRII) is a type 1 transmembrane glycoprotein that mediates several functions including phagocytosis, cytotoxicity, and immunomodulation as well as platelet aggregation. Three genes (A, B, and C) encode CD32 and at least 6 isoforms are generated via alternative mRNA splicing, i.e., IIa1, IIa2, IIb1, IIb2, IIb3 and IIc. Monocytes/macrophages, placental trophoblasts and endothelial cells express all isoforms. In addition, the IIb isoform is expressed by B cells, and the IIa isoform by platelets, granulocytes and, weakly, by B cells. NK cells and neutrophils express Isoform IIc. CD32 binds weakly to the Fc region of monomeric IgG but more strongly to IgG aggregates and immune complexes.

Background

The FCGR2A gene encodes a low affinity immunoglobulin gamma Fc region receptor II-a protein that in isoform 1 is 317 amino acids long at 35 kDA and at isoform 2 is 316 amino acids long at nearly 35 kDA. These proteins are found on the surface of many immune system response cells that act as a low affinity receptor through encouraging responses against pathogens and soluble antigens. Additionally, it functions to initiate phagocytosis of opsonized antigens. FCGR2A participates in Fc-GammaR pathway, osteoclast differentiation, signaling events controlled by PTP1B, and NFAT in immune response. It is known to interact with genes SYK, FYN, HCK, LGALS3, and PIK3R1. FCGR2A is linked to lupus, thrombocytopenia, b-cell lymphomas, otitis media, adult-onset still's disease, guillain-barre syndrome, asymptomatic dengue, severe acute respiratory syndrome.

FAQs for Fc gamma RIIA/CD32a Antibody (NBP2-47831CL1). (Showing 1 - 1 of 1 FAQ).

1. Does any of your FCGR2A antibodies (19C10, 6D11, 13G9) cross react to FCGR2B?
   • For these antibodies, we have used the full-length protein FCGR2A (NP_067674) as the immunogen and we have not mapped the epitope that is detected with each Ab yet. I did an alignment of these two proteins and they are highly conserved thus it seems likely that there will be cross-reactivity.
