app notes :
Immunohistochemistry Procedure . Specimen Preparation: Formalin-fixed, paraffin-embedded tissues are suitable for use with this primary antibody. Deparaffinization: Deparaffinize slides using xylene or xylene alternative and graded alcohols. Antibody Dilution: If using the concentrate format of this product, dilute the antibody 1:50. The dilutions are estimates; actual results may differ because of variability in methods and protocols. Antigen Retrieval: Boil tissue section in 10mM citrate buffer, pH 6.0 for 10 min followed by cooling at room temperature for 20 min. Primary Antibody Incubation: Incubate for 30 minutes at room temperature. Slide Washing: Slides must be washed in between steps. Rinse slides with PBS/0.05% Tween. Visualization: Detect the antibody as instructed by the instructions provided with the visualization system. Immunohistochemistry Dilution: 1:50. IHC Positive Control: Lung. Western Blot . Recommended Starting Protocol: Dilute the antibody 1:25. Incubate for 1 hour at room temperature. The dilution is an estimate; actual results may differ because of variability in methods and protocols. Optimal dilution and procedure should be determined by the end user. Western Blot Positive Control: Kidney Cell Lysate

Immunogen: Synthetic peptide corresponding to C-terminus of human occludin. Control Tissue: Lung. Cellular Localization: Membrane. Entrez Gene Code: 4950. Pathway: Cell Junctions
products description :
Occludin is a 65kDa protein that can exist in a variety of phosphorylated forms, ranging up to approximately 82kDa. This phosphorylation 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.

ncbi summary :
This gene encodes an integral membrane protein that is required for cytokine-induced regulation of the tight junction paracellular permeability barrier. Mutations in this gene are thought to be a cause of band-like calcification with simplified gyration and polymicrogyria (BLC-PMG), an autosomal recessive neurologic disorder that is also known as pseudo-TORCH syndrome. Alternative splicing results in multiple transcript variants. A related pseudogene is present 1.5 Mb downstream on the q arm of chromosome 5. [provided by RefSeq, Apr 2011]
