Western blotting analysis using chromobox 3 antibody (Cat#3777). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with chromobox 3 antibody (Cat#3777, 1:5,000) and HRP-conjugated goat anti-mouse secondary antibody (Cat#101, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
Immunohistochemistry was performed on paraffin-embedded mouse brain using chromobox 3 antibody (Cat#3777, 1:500). Antigen retrieval was done in sodium citrate buffer (pH 6.0). DAB was used for detection, with hematoxylin counterstaining. Images were acquired using a Nikon Ci-L Plus microscope (40× objective). Scale bar: 25 μm.
Immunocytochemical staining of HepG2 cells with Chromobox 3 antibody (Cat#3777, 1:1,000). Nuclei were stained blue with DAPI; Chromobox 3 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: High. Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 0.5% Triton X-100 in 1x PBS. Scale bar: 20 μm.
Flow cytometric analysis of Chromobox 3 expression in HepG2 cells using Chromobox 3 antibody (Cat#3777, 1:2,000). Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 0.5% Triton X-100 in 1x PBS. Green, isotype control; red, Chromobox 3.
