For immunocytochemistry analysis, HeLa cells were fixed and permeabilized for detection of endogenous SMC3 using Anti-SMC3 Recombinant Rabbit Monoclonal Antibody (Product # 703926) at a 1:100 dilution and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a 1:2000 dilution. Panel a) shows representative cells that were stained for detection and localization of SMC3 protein (green), Panel b) is stained for nuclei (blue) using ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). Panel c) represents cytoskeletal F-actin staining using Rhodamine Phalloidin (Product # R415) at a 1:300 dilution. Panel d) is a composite image of Panels a, b and c clearly demonstrating nuclear localization of SMC3. Panel e) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
