Application Abreviews Notes
ICC/IF 1/500 - 1/1000.
WB 1/10000 - 1/50000. Detects a band of approximately 170 kDa (predicted molecular weight: 162 kDa).
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Binds phospholipid vesicles containing phosphatidylinositol 3-phosphate and participates in endosomal trafficking.
    • Sequence similarities

      Contains 1 C2H2-type zinc finger.
      Contains 1 FYVE-type zinc finger.
    • Domain

      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.
    • Cellular localization

      Cytoplasm. Early endosome membrane.

    • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
      Lane 2: Early Endosome Marker 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 - ab109110 observed at 162 kDa. Red - loading control, ab18058, observed at 130 kDa.

      ab109110 was shown to recognize Early Endosome Marker in wild-type HAP1 cells as signal was lost at the expected MW in Early Endosome Marker knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and Early Endosome Marker knockout samples were subjected to SDS-PAGE. Ab109110 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/10000 dilution 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.

    • Immunocytochemistry/Immunofluorescence analysis of JAR (human placenta choriocarcinoma epithelial) cells labelling EEA1 with ab109110 at a dilution of 1/250. Cells were fixed with 4% paraformaldehye and permeabilized with 0.1% TritonX-100. ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG was used as the secondary antibody at a dilution of 1/1000. Counterstained with DAPI and ab195889, anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594), at a dilution of 1/200.

      Image shows cytoplasmic staining in JAR cell line.
