Although a first draft of the human genome is now available, our knowledge of the set of transcripts expressed from this sequence is still far from complete. A new method using ink-jet microarray technology to experimentally test predicted exons provides a genome-based platform for gene identification that bypasses an important limitation of older technologies based on cDNA libraries.
