Data Examples
Detection of Human IRF1 by Western Blot. Western blot shows lysates of Raji human Burkitt's lymphoma cell line, MOLT‑4 human acute lymphoblastic leukemia cell line, and Jurkat human acute T cell leukemia cell line. PVDF Membrane was probed with 0.5 µg/mL of Human IRF1 Monoclonal Antibody (Catalog # MAB4830) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for IRF1 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: IRF1
IRF1 (interferon regulatory factor 1) is a 45 kDa member of the IRF family of proteins. It is induced by TLR9 and INF-gamma stimulation, and positively regulates the expression of IFN-beta, iNOS and 1L-12 p35.  Human IRF1 is 325 amino acids (aa) in length. It contains an N-terminal DNA-binding basic region (aa 1-140) and an acidic C-terminus (aa 141-325). Lys275 and 299 can be SUMOylated, which blocks activity, or ubiquinated at Lys299, which initiates degradation. There is a splice variant that shows an 11 aa substitution for the C-terminal 86 amino acids. Over aa 171-325, human IRF1 shares 83% aa identity with both canine and porcine IRF1.
