Western blotting analysis using STAT1 antibody (Cat#4229). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with STAT1 antibody (Cat#4229, 1:20,000) 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 STAT1 antibody (Cat#4229, 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.
Immunohistochemistry was performed on paraffin-embedded mouse colon tissue using STAT1 antibody (Cat#4229, 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 H9C2 cells with STAT1 antibody (Cat#4229, 1:1,000). Nuclei were stained blue with DAPI; STAT1 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: Medium. Scale bar, 20 μm.
Flow cytometric analysis of STAT1 expression in H9C2 cells using STAT1 antibody (Cat#4229, 1:2,000). Green, isotype control; red, STAT1.
