Heat-mediated antigen retrieval is recommended prior to staining, using a 10mM citrate buffer, pH 6.0, for 10 minutes followed by cooling at room temperature for 20 min. Following antigen retrieval, incubate samples with primary antibody for 30 min at room temperature. A suggested positive control is lung tissue.
Occludin is a 65 kDa protein that can exist in a variety of phosphorylated forms, ranging up to approximately 82 kDa. This phosphorylation is thought to be involved in regulating both localization and the function of Occludin. Polyunsturated 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 tisse; in brain tissue, Occludin is highly and continuously expressed at cell-cell contact sites, whereas non-neural tissues show lower expression and discontinuous distribution.
