Our Abpromise guarantee covers the use of ab2900 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
应用 | Ab评论 | 说明 |

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: EEA1 knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lane 4: NIH3T3 whole cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab2900 observed at 162 kDa. Red - loading control, ab18058, observed at 130 kDa.
ab2900 was shown to recognize EEA1 in wild-type HAP1 cells as signal was lost at the expected MW in EEA1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and EEA1 knockout samples were subjected to SDS-PAGE. Ab2900 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
ICC/IF image of ab2900 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab2900, 1µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).
This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin (Lanes 1-3) or 3% Milk (Lanes 4-6) before being incubated with ab2900 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.
Abcam recommends using milk as the blocking agent. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.

Paraffin embedded sections of human prostate tissue were incubated with ab2900 (1/500 dilution) at room temperature for 30 mins. Antigen retrieval was performed by heat induction in citrate buffer pH 6.
ab2900 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further images can be found at www.proteinatlas.org
Confocal microscopy of fixed primary cultures of rat hippocampal neurons (embryonic day 18) showing immunocytochemical labelling of rabbit polyclonal to EEA1 (ab2900, 1/200; Alexa Fluor 488 1/200; green) and monoclonal mouse anti-β.
ab2900 Rabbit polyclonal to EEA1 (1/500) was used in fixed HEK cells that had been transfected with Rab5-GFP. Fluorescence microscopy of fixed Rab5-transfected HEK cells showing (left to right) immunocytochemical labelling rabbit polyclonal to EEA1 ab2900 (1/500; Alexa Fluor® 568; red), and Rab5-GFP (green) with their overlay (far right). Scale bar = 5µm. Showing little co-localisation as expected.
ab2900 staining mouse L-cells by ICC/IF. Cells were formaldehyde fixed, permeabilized in Triton X-100 and incubated with ab2900 diluted 1/1000 for 1 hour at 37°C. A Cy2® conjugated goat anti-rabbit antibody was used as the secondary.
The Western blot shows that ab14944 reacts strongly with mouse 3T3 and CHO cell lysates. Weak cross-reactivity is seen with Xenopus, mouse brain, mouse liver, rat brain and dog lysates. The antibody does not appear to cross-react with rat liver lysate.
