SUBSTRATE FOR ANALYSIS AND METHOD OF PRODUCING SUBSTRATE FOR ANALYSIS

摘要

PROBLEM TO BE SOLVED: To provide a substrate for analysis which can accurately detect exosome and measure the distribution size of the detected exosome.SOLUTION: A substrate for analysis comprises a substrate 10, and a plurality of pit row groups 20 in which pits 12 formed in concave shape on the surface of the substrate 10 and having an antibody 3 bonding to an antigen 51 existing in exosome 5 as a detection object to be fixed thereto are arranged according to the size.
