Western blotting analysis using macroH2A.1 Histone antibody (Cat#61249). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with macroH2A.1 Histone antibody (Cat#61249, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
Western blotting analysis using macroH2A.1 histone antibody (Cat#61249). MacroH2A.1 histone expression in wild type (WT) and macroH2A.1 histone (H2AFY) shRNA knockdown (KD) HeLa cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with macroH2A.1 histone antibody (Cat#61249, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
Immunohistochemistry was performed on paraffin-embedded human skin tissue using macroH2A.1 histone antibody (Cat#61249, 1:200). 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 HeLa cells using macroH2A.1 Histone antibody (Cat#61249, 1:1,000), Top panel: wild-type (WT); Bottom panal: MacroH2A.1 Histone shRNA knockdown (KD). Nuclei were stained blue with DAPI; MacroH2A.1 Histone was stained magenta with Alexa Fluor® 647. Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 0.5% Triton X-100 in 1x PBS. Scale bar, 20 μm.
Immunocytochemical staining of HAP-1 cells with macroH2A.1 Histone antibody (Cat#61249, 1:1,000). Nuclei were stained blue with DAPI; MacroH2A.1 Histone was stained magenta with Alexa Fluor® 647. 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 macroH2A.1 Histone expression in HAP-1 cells using macroH2A.1 Histone antibody (Cat#61249, 1:2,000). Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 100% Methanol, chill on -20℃ before use. Green, isotype control; red, MacroH2A.1 Histone.
Validation of macroH2A.1 Histone knockdown using flow cytometry. Wild-type(WT, Blue) and knockdown(KD, Green) HeLa cells were stained with macroH2A.1 Histone antibody (Cat#61249, 1:2,000) and analyzed using BD flow cytometer. Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 100% Methanol, chill on -20℃ before use.
