IRF8 Mouse anti-Human, Mouse, APC, Clone: V3GYWCH, eBioscience
Mouse Monoclonal Antibody
Manufacturer: Invitrogen 17985280
Description: The V3GYWCH monoclonal antibody reacts with human and mouse interferon regulatory factor 8 (IRF8; ICSBP). IRF8 is a 50 kDa transcription factor that plays a critical role in the development of dendritic cells (DC). Specifically, IRF8 is essential in the development and differentiation of plasmacytoid DC (pDC) and CD8a+ DC. IRF8-/- mice are deficient in both pDC and CD8a+ DC populations. CD8a- DC are present in normal numbers in IRF8-/- mice but fail to mature upon Toll-like receptor signaling and are functionally impaired in response to in vivo microbial stimulation. IRF8 deficiency does not affect the frequency or viability of DC precursors and as a result retroviral IRF8 transduction restores pDC development from DC progenitors in IRF8-/- mice. Applications Reported: This V3GYWCH antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This V3GYWCH antibody has been tested by intracellular staining and flow cytometric analysis of normal human peripheral blood cells using the Foxp3/Transcription Factor Staining Buffer Set (cat. 00-5523) and protocol. Please refer to Best Protocols: Protocol B: One-step protocol: intracellular (nuclear) proteins located under the Resources Tab online. This can be used at less than or equal to 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. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered. IRF8 (interferon regulatory factor 8) is a transcriptional activator or repressor. It specifically binds to the upstream regulatory region of type I IFN and IFN-inducible MHC class I genes. IRF8 plays a negative regulatory role in cells of the immune system. It is involved in CD8+ dendritic cell differentiation by forming a complex with the BATF-JUNB heterodimer in immune cells. This leads to recognition of AICE sequence, an immune-specific regulatory element, followed by cooperative binding of BATF and IRF8 and activation of the genes. Mutations in the gene can result in immunodeficiencey 32A and 32B.
