Western blot - Anti-Claudin 3 antibody [EPR19971] (ab214487)

All lanes : Anti-Claudin 3 antibody [EPR19971] (ab214487) at 1/1000 dilution

Lane 1 : SW480 (Human colorectal adenocarcinoma cell line) whole cell lysate
Lane 2 : MCF7 (Human breast adenocarcinoma cell line) whole cell lysate
Lane 3 : Caco-2 (Human colorectal adenocarcinoma cell line) whole cell lysate

Lysates/proteins at 10 µg per lane.

Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution

Predicted band size: 23 kDa
Observed band size: 20 kDa
why is the actual band size different from the predicted?

Exposure time: 1 second

Blocking/Dilution buffer: 5% NFDM/TBST.

Doublet bands observed correspond to full length and processed forms of the claudin-3 protein. This is consistent with what has been described in the literature (PMID: 26170992).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Claudin 3 antibody [EPR19971] (ab214487)

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.

Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

Immunocytochemistry/ Immunofluorescence - Anti-Claudin 3 antibody [EPR19971] (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).

Flow Cytometry - Anti-Claudin 3 antibody [EPR19971] (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.
Immunoprecipitation - Anti-Claudin 3 antibody [EPR19971] (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 1/10,000 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.
