Abstract:
1. A biosensor that is made of a single layer or plural layers of a porous material, said biosensor having a reagent holding part which holds a reagent for analyzing an analyte in a liquid specimen having cell components contained therein, said biosensor analyzing target components in the liquid specimen by utilizing chromatography, said biosensor further comprising: a carrier carrying a cell shrinkage reagent having the ability of making the cell components of said liquid specimen shrink on at least a part of an area of said carrier, wherein the cell shrinkage reagent is saccharide, and wherein the shrunk cell components are made smaller by said cell shrinkage reagent, said area ranging from a specimen addition part to which the liquid specimen is added to a reagent holding part thereof; and a reaction layer chromatographically downstream of said carrier on which a reaction between the analyte in the liquid specimen and a reagent eluted from the reagent holding part is carried out, permitting analysis of the analyte in the liquid specimen, wherein the shrunk cell components of said liquid specimen permeate together with the liquid specimen into said reaction layer in a mixed state for analysis to occur.
