| Research Abstract |
We optimized conditions for an in vitro experimental model where we could study interactions between PepT1, peptide transporter expressed on intestinal tract, and its substrate peptide. Purified PepT1 reconstituted on lipid bilayer andcantilever modified with a substrate peptide were prepared and applied to force measurement with atomic force microscopy. An interaction of Au-nanoparticle with Caco-2 monolayer could also be analyzed with dark-field microscopy, suggesting that the PepT1 interaction could be studied using live cells in combination with surface modification of Au with the substrate peptides.
