<P>PROBLEM TO BE SOLVED: To provide a ligand analysis method in a state closer to an actual in-vivo state. <P>SOLUTION: In step S104, a sample substrate arranging a ligand candidate mixed film fraction on an observation area of an antibody immobilization substrate is made. In step S105, a GTP binding protein (G protein) is supplied to the observation area of the sample substrate to measure temporal change in the amount of G protein bound to GPCR. After this, in step S106, a ligand candidate substance as a ligand for G protein coreceptor in the film fraction is analyzed on the basis of the result from the measurement. <P>COPYRIGHT: (C)2012,JPO&INPIT |
