The Invader® platform (Third Wave Technologies Inc., Madison, WI) is a homogeneous, isothermal, DNA probe-based system for highly sensitive, quantitative detection of specific nucleic acid sequences. It is an accurate and specific detection method for single-base changes, insertions, deletions, gene copy number, infectious agents, and gene expression. Invader reactions can be performed directly on genomic DNA- or on RNA-, PCR-, or RT-PCR-amplified products. A target-specific signal is amplified but not the target itself.
