Scientific Data

Western Blot Detection of Human/Mouse IRF2 antibody by Western Blot. View Larger

Detection of Human/Mouse IRF2 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and DA3 mouse myeloma cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse IRF2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4529) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for IRF2 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: IRF2

Interferon Regulatory Factor 2 (IRF2) belongs to the interferon regulatory transcription factor family. IRF2 functions as a regulator of type I interferons by influencing cellular proliferation and immune response through transcriptional regulation. IRF2 competitively inhibits IRF1 gene activation, as well as, stimulating transcription on its own. Overexpression of IRF2 in NIH3T3 cells leads to transformation, whereas, loss of IRF2 expression in knock out mice leads to a variety of abnormalities including loss of NK cells due to increased apoptosis.
