Western blotting analysis using Heat shock transcription factor 1 antibody (Cat#61469). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with Heat shock transcription factor 1 antibody (Cat#61469, 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 Heat shock transcription factor 1 antibody (Cat#61469). Heat shock transcription factor 1 expression in wild type (WT) and heat shock transcription factor 1 shRNA knockdown (KD) 293T cells with 30 μg of total cell lysates. β-Tubulin serves as a loading control. The blot was incubated with Heat shock transcription factor 1 antibody (Cat#61469, 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 ovarian carcinoma using heat shock transcription factor 1 antibody (Cat#61469, 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 HepG2 cells with Heat shock transcription factor 1 antibody (Cat#61469, 1:1,000). Nuclei were stained blue with DAPI; Heat shock transcription factor 1 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: Medium. Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 0.5% Triton X-100 in 1x PBS. Scale bar: 20 μm.
Immunocytochemical staining of 293T cells using Heat shock transcription factor 1 antibody (Cat#61469, 1:1,000), Top panel: wild-type (WT); Bottom panal: Heat shock transcription factor 1 shRNA knockdown (KD). Nuclei were stained blue with DAPI; Heat shock transcription factor 1 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 Heat shock transcription factor 1 expression in HepG2 cells using Heat shock transcription factor 1 antibody (Cat#61469, 1:2,000). Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 100% Methanol, chill on -20℃ before use. Green, isotype control; red, Heat shock transcription factor 1.
Validation of Heat shock transcription factor 1 knockdown using flow cytometry. Wild-type(WT, Blue) and knockdown(KD, Green) 293T cells were stained with Heat shock transcription factor 1 antibody (Cat#61469, 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.
