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.
