Western blot analysis of Daudi

Western blot analysis of Daudi (lane 1) , Raji(lane 2) and A20 (lane 3) cells using IRF4 antibody (clone IRF4.3E4). β-actin antibody (poly6221) was used as loading control.


The IRF family consists of at least nine members. IRF4 and IRF8 are highly homologous to each other and also redundant in function. IRF4 is critical for Th2 and Th17 development. Together with TRF8, it plays an essential role in macrophage and dendritic cell development and function. IRF4 is also reported to be essential for pre-B cell development, receptor editing, germinal center reactor and plasma cell differentiation.

Other Names: Interferon regulatory factor 4
Structure: Molecular weight is approximately 51 kD.
Distribution: IRF4 is reported to be expressed exclusively in the immune system.
