Immunohistochemical analysis of paraffin-embedded human Endometrial carcinoma tissue using Occludin antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P81231, 1:100 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium.

Flow cytometric analysis of 1X106 HepG2 cells labeling Occludin Antibody (HY-P81231, red). Cells were stained with the primary antibody at 1μg/Test dilution for an hour at 4℃. AF488-conjugated Goat Anti-Rabbit IgG H&L (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).

Immunocytochemistry analysis of Caco-2 cells labeling Occludin with Occludin Antibody (HY-P81231) at 1/100 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with quick block buffer for 10 minutes at room temperature. Cells were then incubated with Occludin Antibody (HY-P81231) at 1/100 dilution in quick block buffer overnight at 4 ℃. AF488-conjugated Goat Anti-Rabbit IgG H&L (HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background
-
Function
Occludin may play a role in the formation and regulation of the tight junction (TJ) paracellular permeability barrier. It is able to induce adhesion when expressed in cells lacking tight junctions; (Microbial infection) Acts as a coreceptor for hepatitis C virus (HCV) in hepatocytes
-
Subcellular Localization
Cell membrane; Multi-pass membrane protein; Cell junction, tight junction
-
Expression
Tissue_specificity:It is located at the tight junctions of epithelial and endothelial cells. It is highly expressed in the kidneys. It was not detected in the testes. -

Dephosphorylated by PTPRJ. The tyrosine phosphorylation on Tyr-398 and Tyr-402 reduces its ability to interact with TJP1. Phosphorylation at Ser-490 also attenuates the interaction with TJP1;(Microbial infection) Cleaved by S.pyogenes SpeB protease; leading to its degradation (PubMed:23532847). Degradation by SpeB promotes bacterial translocation across the host epithelial barrier (PubMed:23532847) -
