Flow cytometric analysis of Keratin 7 expression in HepG2 cells using anti-Keratin 7 antibody (Cat#4149, 1:2,000). Green, isotype control; red, Keratin 7.
Immunocytochemical staining of HepG2 cells with anti-Keratin 7 antibody (Cat#4149, 1:1,000) . Nuclei were stained blue with DAPI; Keratin 7 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: High. Scale bar, 20 μm.
Western blotting analysis using anti-keratin 7 antibody (Cat#4149). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with anti-keratin 7 antibody (Cat#4149, 1:10,000) 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 lung adenocarcinoma using anti-glial fibrillary acidic protein antibody (Cat#4149, 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.
