Western blotting analysis using beclin 1 antibody (R020080). Beclin 1 expression in wild type (WT) and beclin 1 (BECN1) shRNA knockdown (KD) HeLa cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with beclin 1 antibody (R020080, 1:5,000) and HRP-conjugated goat rabbit secondary antibody (1:20,000) respectively. Image was developed using ECL Substrate Kit.

Western blotting analysis using beclin 1 antibody (R020080). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with beclin 1 antibody (R020080, 1:5,000) and HRP-conjugated goat rabbit secondary antibody (1:20,000) respectively. Image was developed using ECL Substrate Kit.

Flow cytometric analysis of Beclin 1 expression in HT-1080 cells using Beclin 1 antibody (R020080, 1:2,000). Green, isotype control; red, Beclin 1.

Immunocytochemical staining of HT-1080 cells with Beclin 1 antibody (R020080, 1:1,000). Nuclei were stained blue with DAPI; Beclin 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. Scale bar, 20 μm.

Validation of Beclin 1 knockdown using flow cytometry. Wild-type(WT, Blue) and knockdown(KD, Green) HeLa cells were stained with Beclin 1 antibody (R020080, 1:2,000) and analyzed using BD flow cytometer.
