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
Bit Ability ofepithelial cells attachment of HIV-1 cell-free parAbility of lectins to inhibit attachment of HIV-1 cell-free particles on epithelial cells. HEC-1A cells were co-incubated with non-toxic concentrations of each lectins or mannan (100 /ml) and 5 ng of HIV-1Ba-L (A) or HIV-1NDK (B) virus were added for 1 h. Incubation with mannan was used as control. The quantity of attached virus was
