Abstract:
An assay system for multiplexing together on a single array a plurality of different biological samples having one biological target per sample or a plurality of different biological targets per sample, comprising:an array apparatus that comprises a plurality of first biological probes on a substrate in an array pattern of features, wherein each first probe is different from others in the plurality of first probes, each different first probe is located at a different feature location of the array and is a different address on the array; and a plurality of second biological probes, each second probe comprising a first region and a second region, each second probe being different from others in the plurality of second probes by comprising a different first region, wherein the first region of each second probe is complementary to a different first probe, and the second region of each second probe is complementary to a specific target, such that each second probe addresses a complementary specific target from a different sample of the plurality of different samples being assayed to one of the different addresses on the array corresponding to a respective complementary different first probe.
