Have you ever wondered how those medical test kits (the ones that give you a little plus if you're pregnant, a minus if you're not, for example) work? These are one application of the technology in which we specialize: immunogold labeling and immunoassay tests. This section is intended as an introduction to this technology; take our 'virtual technology tour' below to find out about the science behind such products, check out some results from scientists who have used our probes, and see our news update for a complete listing of recent company news.
