Scientific Data Images for Human IRF4 Antibody

Detection of Human IRF4 by Western Blot.

Western blot shows lysates of Ramos human Burkitt's lymphoma cell line, HDLM-2 human Hodgkin’s lymphoma cell line, U937 human histiocytic lymphoma cell line (negative control), and HUVEC human umbilical vein endothelial cells (negative control). PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human IRF4 Monoclonal Antibody (Catalog # MAB55251) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for IRF4 at approximately 51 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: IRF4

Interferon Regulatory Factor 4 (IRF4), also known as MUM1 and LSIRF, is a 51 kDa lymphocyte-restricted transcription factor. It is required for immunoglobulin class switching and terminal differentiation of B cells. IRF4 is overexpressed in multiple myeloma and cooperates with Myc in an autoregulatory loop. In T cells, IRF4 is required for the production of IL-4. IRF4 contains an N-terminal DNA binding domain that is homologous to that in other IRF proteins. Within the C-terminal domain (aa 130‑451), human IRF4 shares 90% aa sequence identity with mouse and rat IRF4. Alternate splicing may generate isoforms with N-terminal, C-terminal, or internal deletions.
