Occludin Antibody (331594) in ICC/IF

Immunofluorescence analysis of Occludin Antibody, Alexa Fluor® 594 conjugate (OC-3F10) was done on 90% confluent log phase CaCo2 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with Occludin Antibody, Alexa Fluor® 594 conjugate (OC-3F10) (Product # 331594) at 1µg/mL in 1% BSA and incubated for 3 hours at room temperature (Panel a: red). Nuclei (Panel b: blue) were stained with SlowFade® ... View More

Product Specific Information

Reactivity of this antibody with the occludin protein has been confirmed by immunofluorescence and Western blotting (un-conjugated). Tissues/lysates tested: T84 cell line (human intestinal epithelium), MDCK cells (canine kidney), Caco-2 cells (human colon adenocarcinoma), MTE7B (Mouse) and rat liver This antibody reacts specifically with mammalian occludin.

Target Information

Occludin is a 65 kDa protein that can exist in a variety of phosphorylated forms, ranging up to approximately 82 kDa. Occludin is thought to be involved in regulating both the localization and the function of occludin. Polyunsaturated fatty acids are known to up-regulate occludin expression, increasing the transendothelial cell resistance and reducing the cellular permeability to large molecules. The level of occludin varies greatly depending on tissue; in brain tissue, occludin is highly and continuously expressed at cell-cell contact sites, whereas non-neural tissues show lower expression and discontinuous distribution. Overall structural features of the occludin protein are highly conserved in all the species examined. Under-expression of tight junction proteins, including occludin, is a key molecular abnormality responsible for the increased permeability of tumor endothelial tight junctions, which contributes to brain tumor edemas.
