Western blotting analysis using NDUFS1 antibody (Cat#65225). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with NDUFS1 antibody (Cat#65225, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
Western blotting analysis using NDUFS1 antibody (Cat#65225). NDUFS1 expression in wild-type (WT) and NDUFS1 shRNA knockdown (KD) HT-1080 cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with NDUFS1 antibody (Cat#65225, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
Immunohistochemistry was performed on paraffin-embedded human esophageal carcinoma using NDUFS1 antibody (Cat#65225, 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.

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 NDUFS1 antibody (Cat#65225, 1:1,000). Nuclei were stained blue with DAPI; NDUFS1 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 NDUFS1 antibody (Cat#65225, 1:1,000), Top panel: wild-type (WT); Bottom panal: NDUFS1 shRNA knockdown (KD). Nuclei were stained blue with DAPI; NDUFS1 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 NDUFS1 expression in HepG2 cells using NDUFS1 antibody (Cat#65225, 1:2,000). Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 0.5% Triton X-100 in 1x PBS. Green, isotype control; red, NDUFS1.
Validation of NDUFS1 knockdown using flow cytometry. Wild-type(WT, Blue) and knockdown(KD, Green) HT-1080 cells were stained with NDUFS1 antibody (Cat#65225, 1:2,000) and analyzed using BD flow cytometer. Fixative solution: 4% Paraformaldehyde in 1x PBS; Permeabilization solution: 0.5% Triton X-100 in 1x PBS.
