Anti-EEA1 antibody - Early Endosome Marker (ab2900)

Overview

  • Product nameAnti-EEA1 antibody - Early Endosome Marker
    See all EEA1 primary antibodies
  • Description
    Rabbit polyclonal to EEA1 - Early Endosome Marker
  • 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.
  • Tested applicationsICC/IF, IHC (Methanol fixed), IHC-P, WB, ICC, IP, IHC-FoFrmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Hamster, Cow, Dog, Human, Xenopus laevis, Zebrafish, Rhesus monkey, Aplysia
  • Immunogen

    Synthetic peptide derived from within residues 1350 to the C-terminus of Human EEA1.

    (Peptide available as ab14946.)

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.

Anti-EEA1 antibody - Early Endosome Marker images

  • 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-b-tubulin-II (1/400; Alexa Fluor 568 1/200; red). Magnification 63x ; insert 180x.
  • 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).

  • 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. Immunofluorescence microscopy revealed a typically punctuate staining of EEA1 in the HEK cells.

        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

  • 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.
