Western blotting analysis using RAB4A antibody (Cat#62435). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with RAB4A antibody (Cat#62435, 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 RAB4A antibody (Cat#62435). RAB4A expression in wild type (WT) and RAB4A shRNA knockdown (KD) HeLa cells with 20 μg of total cell lysates. β-Tubulin serves as a loading control. The blot was incubated with RAB4A antibody (Cat#62435, 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).
Immunocytochemical staining of HeLa cells with RAB4A antibody (Cat#62435, 1:1,000). Nuclei were stained blue with DAPI; RAB4A 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 RAB4A antibody (Cat#62435, 1:1,000), Top panel: wild-type (WT); Bottom panal: Adiponectin receptor 1 shRNA knockdown (KD). Nuclei were stained blue with DAPI; RAB4A 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.
Validation of RAB4A knockdown using flow cytometry. Wild-type(WT, Blue) and knockdown(KD, Green) HeLa cells were stained with RAB4A antibody (Cat#62435, 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.
