A parallel permeability assay of peptides across artificial membranes and cell monolayers using a fluorogenic reaction
2019
Here, we report a facile permeability assay to quantitatively evaluate the membrane permeability of multiple peptides in parallel. With a fluorogenic click reaction between azidocoumarin and a terminal alkyne tag introduced on a peptide, the peptide that crossed an artificial membrane or a cell monolayer was quantitatively detected. The method allows a rapid measurement of the permeability of multiple compounds on a plate reader even in the presence of a complex mixture of biological molecules.
