Figure 8From: A strategy using NMR peptide structures of thromboxane A2 receptor as templates to construct ligand-recognition pocket of prostacyclin receptorKinetic properties of [3H] iloprost binding to the recombinant IP receptors expressed in COS-7 cells. The cell membrane protein prepared from COS-7 cells that transiently expressed the wild-type (squares), R173A mutant (circles) or R173T mutant (triangles) of the IP receptor was incubated with the increasing concentration of the [3H] iloprost.Back to article page
