DEVICE FOR SAMPLE ANALYSIS AND METHOD FOR EXOSOME CAPTURE

摘要

PROBLEM TO BE SOLVED: To provide a device for sample analysis capable of detecting exosomes with high accuracy to quantitatively measure exosomes secreted by cells.SOLUTION: A recessed/protruding structure 20 in which recessed portions 20a and protruding portions 20b are arranged cyclically is formed on a base part made of synthetic resin or the like. The recessed portions 20a immobilize antibodies 60 that bind with antigens 52 present in exosomes 50 to be detected to bind the exosomes 50 with the antibodies 60. The exosomes 50 are thereby immobilized to the recessed portions 20a.
