Alexzander A. A. Asea,Punit Kaurgene opens a door to potential nonamplified direct detection technologies. In this chapter, a method is described to accurately quantify specific RNA transcripts and thus determine their potential utility as “high-copy” targets. The quantification method described also has application in gene-expression analysis.

Anjali Ramaswamy,Ping Wei,Fan Panleotide fingerprints), is based on high levels of polymorphism observed at several genomic loci in the . genomes that contain small tandemly repeated deoxyribonucleic sequences. The technique described is designed for medium- to high-throughput analyses. However, the method described can be modified to characterize fewer samples.
