Fluorescent test tight junctions

WebTight junctions control paracellular permeability across epithelial cell sheets and also serve as a barrier to intramembrane diffusion of components between a cell's apical and basolateral membrane domains. Epithelial and endothelial cells are joined to each other via a set of intercellular junctions that are important for tissue formation and function. Tight junctions are composed of transmembrane components that mediate adhesion and form the paracellular diffusion barrier. These proteins interact with a … See more Cells are plated to confluence in 12-well tissue culture inserts and are left for at least 5 days to form differentiated monolayers, with the medium being replaced every … See more When analyzing tight junctions, it is required to test for expression/ localization of protein markers as well as to assay for paracellular gate … See more Neither TER nor tracer permeability measurements alone reflect the paracellular pathway properties, but both are a composite of the paracellular and transcellular routes.
