Scientific Background
Interferon Regulatory Factor 5 (IRF5) is a member of the IRF family. It contains one IRF tryptophan pentad repeat DNA-binding domain. IRF5 shuttles between the nucleus and the cytoplasm. IRF5 can form homodimer when it is phosphorylated. IRF5 functions as a transcription factor involved in the induction of interferons IFNA and INFB and inflammatory cytokines upon virus infection. Genetic variations in IRF5 are associated with susceptibility to systemic lupus erythematosus type 10. In addition, the genetic variations wil result in susceptibility to rheumatoid arthritis.

Safety & Handling
Research use only
This protein was produced in E. coli. Mammalian expression enables human-like glycosylation, correct disulfide bond formation, and proper protein folding — all critical for proteins used in binding interaction studies (SPR/BLI) and antibody characterisation. For transmembrane proteins expressed as ectodomains or nanodisc preparations, the expression system directly affects binding conformation and assay performance.
The expressed amino acid region is specified in the protein specifications table. Cross-reference with the UniProt entry (Q13568) to confirm the expressed region includes your domain of interest — receptor-binding domain, extracellular domain, or specific epitope — before ordering.
Greater than 95% as determined by reducing SDS-PAGE.. A gel image showing the protein band is provided with each lot on the Certificate of Analysis. This high-purity specification is suitable for SPR/BLI kinetics measurements, ELISA standard curve development, and antibody epitope binding studies.
Please refer to the Certificate of Analysis (CoA) for reconstitution instructions for your specific lot. Storage: Store at ≤-70°C, stable for 6 months after receipt. Store at ≤-70°C, stable for 3 months under sterile conditions after opening. Please minimize freez Prepare single-use working aliquots after reconstitution to avoid repeated freeze-thaw cycles. Lyophilized protein is stable for 12 months at −80°C from the date of receipt.
