摘要： An analysis film comprises a reagent layer composed of a porous material which contains an antibody but does not substantially contain a complex of an analyte or a labelled antigen with the antibody. In the analysis film, reagents for enzyme immune reaction of homogenous type are incorporated so that an analyte is analyzed without requiring B/F separation. An analysis method for various analytes using the same provides high sensitivity, high accuracy as well as good reproducibility and is simple and rapid.
