IMMUNOSENSOR AND DETERMINATION METHOD USING THE SAME

摘要

An immunosensor comprising: a base body (101) having a sample-holding unit (102) for holding a sample to be tested; a sample inlet (103) through which the sample is introduced into the sample-holding unit (102) and which is provided in communication with the sample-holding unit (102); a first reagent (109) which is in a dried form and contains an antibody directed against a substance to be determined contained in the sample; and a second reagent (110) which is in a dried form and contains polyethylene glycol, wherein the first reagent (109) is placed in the sample-holding unit (102) in such a manner that the first reagent (109) is positioned closer to the sample inlet (103) than the second reagent (110).
