Abstract:
A method for preparing supports for assaying a chemical or biological substance, said supports each having an ordered set of reaction zones, the method comprising:(a) preparing a set of homogeneous strips for each reaction zone, (b) grouping several of said strips from step (a) substantially edge to edge so as to prepare intermediate supports which, along an axis perpendicular to said strips, comprise alignments of different reaction zones, and which, along a second axis comprise alignments of identical reaction zones, (c) cutting each intermediate support into a second set of strips, having substantially the same width, each of said strips from the second set of strips comprising one of said alignments of different reaction zones, and (d) grouping the strips from step (c) each comprising an alignment of different reaction zones substantially edge to edge so as to form assay supports each having alignments of ordered reaction zones of different types.
