Multi-spot enzyme immunoassay method |
摘要 |
An assay for an immunologically active substance (B) in a biologically derived test sample comprising using an immuno-active membrane of a hydrophobic polymer sheet having numerous hydrophilic spots, on which a prefixed amount of an immuno-active substance (A) or (B) has been immobilized, and a coloring-membrane having numerous spots which contain a color-producing reagent being capable of developing color by the catalytic effect of an enzyme at the corresponding positions to those of the immuno-active membrane, and making contact the immuno-active membrane with said test sample in the presence of an enzyme-labeled immuno-active substance (A') or (B') and a substrate for reacting the substance (A), substance (B) and enzyme-labeled substance (A') or (B') competitively or non-competitively, and superposing the coloring-membrane of on the immuno-active membrane, followed by colorimetrically measuring the resulting color and thereby determining the amount of the substance (B) in the test sample.
