For immunofluorescence analysis, HeLa cells were fixed and permeabilized for detection of endogenous TAX1BP1 using Anti- TAX1BP1 Recombinant Rabbit Monoclonal Antibody (Product # 702840, 1:100 dilution) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000 dilution). Panel a) shows representative cells that were stained for detection and localization of TAX1BP1 protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). Panel c) represents cytoskeletal F-actin staining using Rhodamine Phalloidin (Product # R415, 1:300). Panel d) is a composite image of Panels a, b and c clearly demonstrating cytoplasmic localization of TAX1BP1. Panel e) represents control cells without primary antibody to assess background. The images were captured at 60X magnification.
