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 (Product # 00-5523-00) 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 0.5 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.
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 (Product # 00-822-49) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333-54) 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: 0.2 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.
