  ab137029 was shown to specifically react with RAB7 in wild-type HAP1 cells. No band was observed when RAB7 knockout samples were examined. Wild-type and RAB7 knockout samples were subjected to SDS-PAGE. ab137029 and Anti-GAPDH antibody [6C5] - Loading Control ab8245 (loading control to GAPDH) were both diluted 1/1000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1/10 000 dilution for 1 hour at room temperature before imaging.

  Immunocytochemistry/Immunofluorescence analysis of HeLa (human epithelial cell line from cervix adenocarcinoma) labelling RAB7 with purified ab137029 at 1/500. Cells were fixed with 100% methanol. An Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077). Nuclei counterstained with DAPI (blue).

  Flow Cytometry (Intracellular) - Anti-RAB7 antibody [EPR7589] (ab137029)

  Overlay histogram showing HAP1 wildtype (green line) and HAP1-RAB7 knockout cells (red line) stained with ab137029. The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab137029, 0.1μg/ml) for 30 min at 22°C. The secondary antibody used was Alexa Fluor^® 488 goat anti-rabbit IgG (H&L) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081) at 1/2000 dilution for 30 min at 22°C. A rabbit IgG1 isotype control antibody (Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab172730) was used at the same concentration and conditions as the primary antibody (HAP1 wildtype - black line, HAP1-RAB7 knockout - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity). Acquisition of >5,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter. This antibody can also be used in HAP1 cells fixed with 80% methanol (5 min) permeabilized with 0.1% PBS-Triton X-100 for 15 min under the same conditions.

  ab137029 staining RAB7 in Human HepaRG cell by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with formaldehyde, permeabilized with 0.1% Triton X-100 in PBS and blocked with 1% milk for 30 minutes at room temperature. Samples were incubated with primary antibody (1/200 in 1% milk) for 30 minutes. An Alexa Fluor®488-conjugated Donkey anti-rabbit IgG polyclonal (1/400) was used as the secondary antibody.
