When it comes to gene-expression analysis, researchers seem always to be sacrificing something. With real-time quantitative PCR, it's gene number: Though inexpensive enough to apply to large numbers of samples, each assay can test, at best, three or four transcripts simultaneously. Microarrays, on the other hand, sacrifice sample throughput, probing tens of thousands of genes in a single sample.

Key to the Mosaic system is a set of addressable magnetic spheres called Qbead™ microspheres. Each Qbead is coated with a precise blend of quantum dots that gives the bead a unique color; this identifies the bead and by extension, the assay being performed on ...
