there is a great concern about the effect of propoxur, as one of the more common n-methyl carbamate pesticides, on human health due to its extensive use in agricultural and non-agricultural applications. caco-2 cells became resistant to propoxur, and the resistance was confirmed through mtt assay. then the cell membrane integrity and p-glycoprotein expression were measured by ldh assay and west...

A new sandwich-type enzyme-linked immunosorbent assay for quantifying glycocalicin, a proteolytic fragment of platelet membrane glycoprotein Ib, is described. The assay is based on the use of two monoclonal antibodies raised against glycoprotein Ib and involves the avidin-biotin technique. The detection limit is 7 micrograms/L and the range of glycocalicin determined in plasma is 0.01 to 1 mg/L...

Human gall bladder mucus glycoprotein was isolated by Sepharose 4B gel filtration followed by caesium chloride density gradient ultracentrifugation from four groups: patients with cholesterol gall stones, patients with pigmented stones, patients with complete obstruction of the cystic duct and patients with no biliary tract abnormalities (controls). Mucus glycoprotein concentrations in choleste...
