Immunocytochemistry/Immunofluorescence analysis of Plectin in U20S cells using Plectin Polyclonal Antibody (Product # PA5-79829). Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent for 15 mins. The cells were blocked with 10% goat serum and incubated with the primary antibody at 5 µg/mL. DyLight 488 conjugated goat anti-rabbit IgG was used as secondary antibody at 1:500 dilution and incubated for 30 minutes at 37°C. The section was counterstained with DAPI.
