  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Galactose-specific lectin which binds IgE. May mediate with the alpha-3, beta-1 integrin the stimulation by CSPG4 of endothelial cells migration. Together with DMBT1, required for terminal differentiation of columnar epithelial cells during early embryogenesis.
    • Tissue specificity

      A major expression is found in the colonic epithelium. It is also abundant in the activated macrophages.
    • Sequence similarities

      Contains 1 galectin domain.
    • Cellular localization

      Nucleus. Cytoplasmic in adenomas and carcinomas. May be secreted by a non-classical secretory pathway and associate with the cell surface.

    • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: Galectin 3 (KO) knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HeLa whole cell lysate (20 µg)
      Lane 4: MCF7 whole cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab76466 observed at 35 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab76466 was shown to specifically react with Galectin 3 (KO) when Galectin 3 (KO) knockout samples were used. Wild-type and Galectin 3 (KO) knockout samples were subjected to SDS-PAGE. Ab76466 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 2000 dilution and 1/10000 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 1/20000 dilution for 1 hour at room temperature before imaging.

    • Overlay histogram showing THP1 cells stained with ab76466 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% human serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab76466, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
