Description

Interferon regulatory factor 7 (IRF7) serves as a master regulator of type I interferon-dependent immune responses, playing a critical role in antiviral defense and innate immunity signaling pathways. This transcription factor is essential for the amplification of interferon production following viral infection, making it a key target for researchers investigating immune regulation, viral pathogenesis, and inflammatory diseases.

This recombinant monoclonal antibody against human IRF7 offers the reproducibility and consistency that demanding experimental workflows require. Generated using recombinant technology with clone 17A5, the antibody provides sequence-defined specificity that eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived reagents. The rabbit IgG format, raised against a synthetic peptide derived from human IRF7, ensures reliable target recognition across your experimental timeline.

Validation studies confirm robust performance in flow cytometry applications, with recommended dilutions ranging from 1:50 to 1:200. Testing in A549 human lung carcinoma cells demonstrated clear positive signal separation from isotype control, with cells fixed in formaldehyde and permeabilized with Triton X-100 to enable detection of this intracellular transcription factor. The antibody has also been validated for ELISA applications, providing flexibility for researchers employing multiple detection strategies within their studies.

Supplied in a stabilized liquid format with glycerol for convenient long-term storage at -20°C or -80°C, this affinity-purified antibody is ready for immediate use in your experiments. Whether investigating interferon signaling cascades, characterizing immune cell activation states, or exploring IRF7's emerging roles in autoimmune conditions and cancer immunology, this antibody delivers the technical reliability your research demands.

Target Background

Function

Key transcriptional regulator of type I interferon (IFN)-dependent immune responses and plays a critical role in the innate immune response against DNA and RNA viruses. Regulates the transcription of type I IFN genes (IFN-alpha and IFN-beta) and IFN-stimulated genes (ISG) by binding to an interferon-stimulated response element (ISRE) in their promoters. Can efficiently activate both the IFN-beta (IFNB) and the IFN-alpha (IFNA) genes and mediate their induction via both the virus-activated, MyD88-independent pathway and the TLR-activated, MyD88-dependent pathway. Induces transcription of ubiquitin hydrolase USP25 mRNA in response to lipopolysaccharide (LPS) or viral infection in a type I IFN-dependent manner. Required during both the early and late phases of the IFN gene induction but is more critical for the late than for the early phase. Exists in an inactive form in the cytoplasm of uninfected cells and following viral infection, double-stranded RNA (dsRNA), or toll-like receptor (TLR) signaling, becomes phosphorylated by IKBKE and TBK1 kinases. This induces a conformational change, leading to its dimerization and nuclear localization where along with other coactivators it can activate transcription of the type I IFN and ISG genes. Can also play a role in regulating adaptive immune responses by inducing PSMB9/LMP2 expression, either directly or through induction of IRF1. Binds to the Q promoter (Qp) of EBV nuclear antigen 1 a (EBNA1) and may play a role in the regulation of EBV latency. Can activate distinct gene expression programs in macrophages and regulate the anti-tumor properties of primary macrophages.
