DescriptionRabbit polyclonal to EEA1 - Early Endosome Marker
-
Host speciesRabbit
-
SpecificityDetects a band at 180kDa that represents EEA1 in Western blotting on human cell lines (corresponds to results seen in Mu et al). Also detects a band at 100kDa, we are unsure as to the identity of this band. Immunofluorescence staining of EEA1 in HeLa cells yields a punctate staining pattern consistent with the cytoplasmic distribution of endosomes.

Applications
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.
Application | Abreviews | Notes |
---|---|---|
ICC/IF | Use a concentration of 1 µg/ml. | |

Target
-
FunctionBinds phospholipid vesicles containing phosphatidylinositol 3-phosphate and participates in endosomal trafficking.
-
Sequence similaritiesContains 1 C2H2-type zinc finger.
Contains 1 FYVE-type zinc finger. -
DomainThe FYVE-type zinc finger domain mediates interactions with phosphatidylinositol 3-phosphate in membranes of early endosomes and penetrates bilayers. The FYVE domain insertion into PtdIns(3)P-enriched membranes is substantially increased in acidic conditions.
-
Cellular localizationCytoplasm. Early endosome membrane.

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).

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.

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 160 kDa
Observed band size: 180 kDa why is the actual band size different from the predicted?
Additional bands at: 100 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 30 secondsThis 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

Exposure time: 30 secondsThe 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.
