Patent ID: 7285242

Claim:
A biochemical analysis unit comprising a substrate made of a metal material which attenuates radiation energy and/or light energy and formed with a plurality of holes, and a plurality of absorptive regions formed by charging an absorptive material in the plurality of holes formed in the substrate, the plurality of absorptive regions being selectively labeled with at least one kind of labeling substance selected from a group consisting of a radioactive labeling substance, a labeling substance which generates chemiluminescent emission when it contacts a chemiluminescent substrate and a fluorescent substance by spotting specific binding substances whose sequence or composition are known therein and specifically binding a substance derived from a living organism and labeled with at least one kind of said labeling substance with the specific binding substances wherein the absorptive region is formed of a material selected from the group consisting of a fiber material and a porous material, including a carbon material or a material adapted for forming a membrane filter and wherein the substance derived from a living organism is specifically bound with specific binding substances by a reaction selected from a group consisting of hybridization antigen-antibody reaction and receptor-ligand reaction.
