CD307d (FcRL4), PerCP-eFluor 710, clone: 413D12, eBioscience
Mouse Monoclonal Antibody
Manufacturer: Invitrogen 46307941
This gene encodes a member of the immunoglobulin receptor superfamily and is one of several Fc receptor-like glycoproteins clustered on the long arm of chromosome 1. The encoded protein has four extracellular C2-type immunoglobulin domains, a transmembrane domain and a cytoplasmic domain that contains three immune-receptor tyrosine-based inhibitory motifs. This protein may play a role in the function of memory B-cells in the epithelia. Aberrations in the chromosomal region encoding this gene are associated with non-Hodgkin lymphoma and multiple myeloma.Description: The 413D12 monoclonal antibody reacts with human CD307d, which is also known as FcRL4, Fc receptor-like 4, FcRH4, IRTA4, or IGFP2. CD307d is an inhibitory receptor that is highly expressed on a subset of memory B cells resident in epithelial tissues and marginal zones of mucosal lymphoid tissues such as tonsils. CD307d has been shown to recruit the phosphatase SHP-1, thereby acting as an inhibitory receptor in B cells. CD307d is homologous to FcgammaRI and specifically binds IgA. To date, CD307d is the only known inhibitory receptor for IgA. Expression of CD307d is increased on memory B cells from patients with chronic infections such as HIV, suggesting that enhanced expression of inhibitory receptors, such as CD307d, may contribute to the inefficiency of antibody responses against HIV.Applications Reported: This 413D12 antibody has been reported for use in flow cytometric analysis.Applications Tested: This 413D12 antibody has been pre-titrated and tested by flow cytometric analysis of human tonsil tissue or transfected 293T cells. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome.Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.Excitation: 488 nm; Emission: 710 nm; Laser: Blue Laser.Filtration: 0.2µm post-manufacturing filtered.
