Multiplex assay strip, beads, device and method

A system comprising at least a first strip and a second strip for use in multiplex analyte analyses, enrichment or purification, each strip comprising a bar member, a plurality of spaced-apart rod members extending from the bar member, and a plurality of macro beads, each macro bead being attached to a respective one of the rod members, the bar member having a length equal to or longer than the width of a device with which the strip is capable of being used, a width of the bar member and a width of each rod member being the same, each macro bead having a surface that can accept a coating of a substance, which when subjected to a procedure, can interact or react with an analyte and provide a result of analysis, enrichment or purification for the analyte,

• wherein the bar member, the plurality of spaced-apart rod members and the plurality of macro beads are unitarily formed, and
• wherein positions of the plurality of macro beads of the first strip are shifted relative to positions of the macro beads of the second strip, the shift in positions being sufficient to allow at least one of the macro beads from the first strip and at least one of the macro beads from the second strip to be located in a single well of a device to mix with a sample provided in the single well so as to enable the multiplex analyte analyses.
