特异性
Detects 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. -

常规说明
The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.
One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

靶标
-
功能
Binds phospholipid vesicles containing phosphatidylinositol 3-phosphate and participates in endosomal trafficking. -
序列相似性
Contains 1 C2H2-type zinc finger.
Contains 1 FYVE-type zinc finger. -
结构域
The 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. -

ICC/IF image of ab2900 stained human HeLa (Human epithelial cell line from cervix adenocarcinoma) 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 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.

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.
