Target

  • Function
    May function as a growth factor receptor.
  • Tissue specificity
    Placenta, pancreatic carcinoma cell lines.
  • Involvement in disease
    Defects in TACSTD2 are the cause of gelatinous drop-like corneal dystrophy (GDLD) [MIM:204870]; also known as lattice corneal dystrophy type III. GDLD is an autosomal recessive disorder characterized by grayish corneal amyloid deposits that cause severe visual impairment.
  • Sequence similarities
    Belongs to the EPCAM family.
    Contains 1 thyroglobulin type-1 domain.
  • Post-translational
    modifications
    The N-terminus is blocked.
  • Cellular localization
    Membrane.

Anti-TROP2 antibody [162-46.2] images

  • MCF7 cells stained for TROP2 (colored green) using ab79976 in ICC/IF. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab79976, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • Overlay histogram showing MCF7 cells stained with ab79976 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab79976, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive result in 4% paraformaldehyde (10 min) fixed MCF7 cells used under the same conditions.

    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.
