Immunofluorescent analysis of HA Tag was performed using HA-H3 construct transfected in HEK-293E cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with HA Tag Monoclonal Antibody (2-2.2.14) (Product # 26183) at 2 µg/mL and Histone H3 Rabbit Polyclonal Antibody (Product # 711055) at 0.5 µg/mL in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Goat anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 555 (Product # A32727) and Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32790) respectively at a dilution of 1:2,000 for 45 minutes at room temperature. Panel a (Nuclei: Red) represents HA Tag Monoclonal Antibody. Panel b (Nuclei: Green) represents Histone H3. Panel c (Nuclei: Blue) represents ProLongTM Diamond Antifade Mountant with DAPI (Product # P36962). Panel d represents the merged image showing the co-localization of nuclear signals in transfected cells. Panel e represents untransfected HEK cells. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
