Target

  • Function

    Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity.
  • Involvement in disease

    Note=CLDN3 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region.
  • Sequence similarities

    Belongs to the claudin family.
  • Cellular localization

    Cell junction > tight junction. Cell membrane.

Images

  • Immunohistochemical analysis of paraffin-embedded human pancreas tissue labeling Claudin 3 with ab214487 at 1/250 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Membrane staining on the pancreatic acinar cells of human pancreas is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214487).

  • Immunohistochemical analysis of paraffin-embedded human prostate tissue labeling Claudin 3 with ab214487 at 1/250 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Membrane staining on the epithelium of human benign prostatic hyperplasia is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214487).

  • Immunohistochemical analysis of paraffin-embedded human breast cancer tissue labeling Claudin 3 with ab214487 at 1/250 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Membrane staining on the tumor cells of human breast cancer is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214487).

  • Immunofluorescent analysis of 100% methanol-fixed MCF7 (Human breast adenocarcinoma cell line) cells labeling Claudin 3 with ab214487 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing membrane staining on MCF7 cell line. The nuclear counterstain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) ab195889) at 1/200 dilution (red).

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) at 1/1000 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214487).

  • Flow cytometric analysis of 4% paraformaldehyde-fixed MCF7 (Human breast adenocarcinoma cell line) cells labeling Claudin 3 with ab214487 at 1/50 dilution (red) compared with Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730; black) and an unlabelled control (cells without incubation with primary antibody and secondary antibody; blue). Goat Anti-Rabbit IgG (Alexa Fluor® 488) at 1/2000 dilution was used as the secondary antibody.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214487).

  • Claudin 3 was immunoprecipitated from 0.35 mg of MCF7 (Human breast adenocarcinoma cell line) whole cell lysate with ab214487 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab214487 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: MCF7 whole cell lysate 10µg (Input).

    Lane 2: ab214487 IP in MCF7 whole cell lysate.

    Lane 3:Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) instead of ab214487 in MCF7 whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 3 seconds.
