<p>It is an object of the present invention to conduct function analysis of proteins arranged with high density on a solid phase in a high-throughput manner, regardless of protein varieties. The present invention is characterized in that it immobilizes target proteins on a substrate while maintaining the structures and the functions thereof, and that it carries out interaction analysis of such proteins. For example, target proteins are prepared in a state where one end of each protein is fused to a peptide as a tag or to a polypeptide by genetic engineering methods. Then, the target proteins are bonded to the substrate via a layer formed thereon, comprising anti-tag antibodies. The target proteins are arrayed while they are maintained in a liberated state on a solid phase, and the interaction analysis is carried out. According to the present invention, the interaction analysis of target proteins can be carried out without affecting the unstable structures and the functions thereof. For example, the present invention can be applied as a platform for interaction analysis, screening, quantitation, expression profiling, or the like, regarding proteins.</p> |
