IHC image of CSB-PA016263LA01HU diluted at 1:400 and staining in paraffin-embedded human colon cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Immunofluorescence staining of MCF-7 cells with CSB-PA016263LA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

產品描述：

The OCLN antibody is a polyclonal IgG antibody developed in a rabbit. The immunogen is the recombinant human OCLN protein (285-430aa). The purity of this OCLN antibody exceeds 95% using protein G purification. This OCLN antibody is specifically reactive with human species. The reactivity of this OCLN antibody with the OCLN protein has been confirmed by ELISA, WB, IHC, and IF assays.

The OCLN protein mainly forms tight junctions between adjacent epithelial and endothelial cells and plays a crucial role in maintaining the integrity of the blood-brain barrier. OCLN protein has also been implicated in signal transduction, cell adhesion, and cell migration. Dysregulation of OCLN expression or function can lead to various pathological conditions, including inflammatory bowel disease, viral infections, and cancer.
