For immunofluorescence analysis, SH-SY5Y cells were fixed and permeabilized for detection of endogenous TMEM175 using Anti-TMEM175 Recombinant Rabit Monoclonal Antibody (Product # 703805, 1:100 dilution) and labeled with Goat anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 conjugate (Product # A32731, 1:2000). Panel a) shows representative cells that were stained for detection and localization of TMEM175 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, 1:300). Panel d) is a composite image of Panels a, b and c clearly demonstrating cytoplasmic and vesicular localization of TMEM175. Panel e) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
