摘要
We have developed a novel bioassay method for the detection of snake venom based on the permeability of endothelial cell monolayers cultured in Transwell cell culture inserts. This assay relies on the proteolytic degradation of capillary basement membrane proteins, a pathophysiological event that occurs due to snakebites in vivo. Transwell permeability assays with fluorescence measurements are advantageous with regard to ethical considerations for the use of animals. The assay time was reduced from 24 h for animal tests to 2 h, and many samples could be assayed easily.
