Compared with those of standard OD490 versus cell number curves generated for each cell type. The percentage survival was calculated using the formula :Epithelial monolayer integrity the effect of the plant lectins on their ability to maintain an intact epithelium was determined by measuring transepithelial resistance (TER). HEC-1A cells were grown as a tight polarized monolayer on a permeable sup
Or media alone were added in duplicate wells, and the TER was measured at 30 min and 2, 4, 9, and 24 h. The epithelial resistance was expressed as follows :epithelial resistance = (/cm2) - the resistance of transwells without cells.HIV cell-free particles transcytosis the epithelial cell line HEC-1A was grown as a tight polarized monolayer on a permeable support of 0.4- -porediameter polycarbonate
