Western blotting analysis using keratin 8 antibody (Cat#71285). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with keratin 8 antibody (Cat#71285, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using FeQ™ ECL Substrate Kit (Cat#226).
Western blotting analysis using keratin 8 antibody (Cat#71285). Keratin 8 expression in wild-type (WT) and keratin 8 (KRT8) knockout (KO) HeLa cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with keratin 8 antibody (Cat#71285, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using FeQ™ ECL Substrate Kit (Cat#226).
Immunohistochemistry was performed on paraffin-embedded human breast carcinoma using keratin 8 antibody (Cat#71285, 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.
