Western blotting analysis using pro Caspase 3 antibody (Cat#67673). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with pro Caspase 3 antibody (Cat#67673,1:10,000) and HRP-conjugated goat anti rabbit secondary antibody (Cat#201,1:50,000) respectively. Image was developed using FeQ™ ECL Substrate Kit (Cat#226).
Western blotting analysis using pro Caspase 3 antibody (Cat#67673). pro Caspase 3 expression in wild type (WT) and pro Caspase 3 shRNA knockdown (KD) HeLa cells with 30 μg of total cell lysates. β-Tubulin serves as a loading control. The blot was incubated with pro Caspase 3 antibody (Cat#67673,1:10,000) and HRP-conjugated goat anti rabbit secondary antibody (Cat#201,1:50,000) respectively. Image was developed using FeQ™ ECL Substrate Kit (Cat#226).
Immunohistochemistry was performed on paraffin-embedded human tonsillitis using pro caspase 3 antibody (Cat#67673, 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 C2C12 cells with pro Caspase 3 antibody (Cat#67673, 1:1,000). Nuclei were stained blue with DAPI; Pro Caspase 3 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 HeLa cells using pro Caspase 3 antibody (Cat#67673, 1:1,000), Top panel: wild-type (WT); Bottom panal: pro Caspase 3 shRNA knockdown (KD). Nuclei were stained blue with DAPI; pro Caspase 3 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 pro Caspase 3 expression in HT-1080 cells using pro Caspase 3 antibody (Cat#67673,1:2,000). Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 100% Methanol, chill on -20℃ before use. Green, isotype control; red, pro Caspase 3.
Validation of pro Caspase 3 knockdown using flow cytometry. Wild-type(WT, Blue) and knockdown(KD, Green) HeLa cells were stained with pro Caspase 3 antibody (Cat#67673, 1:2,000) and analyzed using CytoFLEX. Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 100% Methanol, chill on -20℃ before use.
