Figure 1: Western blot analysis using Occludin antibody against HepG2(1) cell lysate.12% SDS-PAGE gel.Sample loading: 20μg /lane. Transfer the proteins onto a PVDF membrane (OM790003), and block it with TBST (OM750016) plus skimmed milk powder(OM750084) for one hour. Dilute the primary antibody with the antibody diluent (OM750012) at a ratio of 1:1000, and incubate it overnight at 4°C. Wash the membrane three times with TBST (OM750016), 5 minutes each time. At room temperature, dilute the secondary antibody, Goat Anti-Rabbit IgG(H&L)-HRP (OM643487), at a ratio of 1:20000 and incubate for one hour. Wash the membrane three times with TBST (OM750016) again, 5 minutes each time. Use ECL (OM625701) for luminescence.staining time: 60S.IHC

Wash the sections with ddH₂O and PBS (OM750003). Block the tissue with 10% non-immune goat serum(OM760028) at room temperature for 30 minutes. Incubate the tissue with the primary antibody diluted at a ratio of 1:1500 at 4°C overnight. At room temperature, dilute the secondary antibody, Goat Anti-Rabbit IgG(H&L)-HRP (OM643487), at a ratio of 1:200 and incubate for one hour. Use DAB(OM760029)as the chromogenic agent. Counterstain the tissue with hematoxylin, and mount the tissue sections with neutral gum.ICC/IF

Red: Actin filaments have been labeled with Omnimabs® 594-Phalloidin.Cells are fixed in 4% paraformaldehyde at room temperature for 20 minutes. Then, they are permeabilized with a PBS (OM750003) solution containing 0.1% Triton X-100(OM750021) at room temperature for 15 minutes. Subsequently, the cells are blocked with 10% non - immune goat serum(OM760028) at room temperature for 1 hour.The cells are incubated overnight at 4°C with the primary antibody diluted 1:100 in PBS. The secondary antibody, Omnimabs® 488 Goat Ant-Rabbit IgG(H&L) (Green,OM643486), is diluted at a ratio of 1:400 and incubated with the cells for 1 hour.Nuclear DNA is labeled with DAPI (Blue,OM643160).

| Gene 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] |
