The polyclonal antibody reacts with human occludin, an integral membrane protein specifically associated with tight junctions. These specialized regions of the plasma membrane prevent the diffusion of dissolved molecules between adjacent epithelial cells, seal off body cavities such as intestine or stomach lumen and prevent the diffusion of membrane proteins and glycolipids between the apical and basolateral regions of the plasma membrane. Occludin is localized at tight junctions of both epithelial and endothelial cells and is highly expressed in kidney and has not been detected in testis. On the cytoplasmic surface of occludin, a domain within the C-terminal 150 residues has been shown to bind directly to the well-characterized tight junction protein zona occludens 1 (ZO-1). The antibody is generated against recombinant human occludin (aa 358-504). The polyclonal anti-human occludin antibody cross reacts with rat, mouse and dog occludin.

Frozen sections, Immuno fluorescence, Western blot

For immunohistology, immunfluorescence and Western blotting, dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50..

  • New Human Complement Pathway Assays
    We are very proud of our newly developed human classical and alternative complement pathway assays. They are produced in response to a growing demand for quantitative investigation of complement inhibitors or regulators at lower sample dilutions. This development aims to address the issue of false negative results, enabling more accurate and reliable analysis of complement… Read more: New Human Complement Pathway Assays
  • Navigating the pitfalls in complement analysis
    Our colleague Erik Toonen shared his experience on how to analyze complement at the Complement-based Drug Development Summit in Boston in September 11-13th, 2023. He showed valuable insights on analyzing complements. For accurate complement analysis, it is important that not only the correct technique is used but also that pre-analytical sample handling is performed in… Read more: Navigating the pitfalls in complement analysis
  • NEW Human C3d ELISA
    We are happy to introduce our new ELISA (cat.# HK3017) designed to detect human C3d. What sets this assay apart is its utilization of a distinctive neo-epitope capture antibody that selectively targets a specific C3d region of the alpha chain, which is not available in other C3 variants. This way it specifically distinguishes C3d from native C3… Read more: NEW Human C3d ELISA
