We are constantly working hard to ensure we provide our customers with best in class antibodies. As a result of this work we are pleased to now offer this antibody in purified format. We are in the process of updating our datasheets. The purified format is designated 'PUR' on our product labels. If you have any questions regarding this update, please contact our Scientific Support team.
This product is a recombinant rabbit monoclonal antibody.
Our Abpromise guarantee covers the use of ab108974 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/2000 - 1/10000. Detects a band of approximately 25 kDa (predicted molecular weight: 24 kDa).|
|ICC/IF||1/100 - 1/250.|
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: Rab4 knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: Human fetal brain cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab108974 observed at 24 kDa. Red - loading control, ab8245, observed at 37 kDa.
Unpurified ab108974 was shown to recognize Rab4 when Rab4 knockout samples were used, along with additional cross-reactive bands. Wild-type and Rab4 knockout samples were subjected to SDS-PAGE. Unpurified ab108974 and ab8245 (loading control to GAPDH) were both diluted 1/2000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.
Blocking and diluting buffer: 5% NFDM/TBST
Immunocytochemistry/ Immunofluorescence analysis of MCF7 (Human breast adenocarcinoma epithelial cell) cells labeling Rab4 with purified ab108974 at 1:100 dilution (8.8μg/ml). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1:200 (2.5 μg/ml). ab150077 Goat anti rabbit IgG(Alexa Fluor® 488) was used as the secondary antibody at 1:1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.
