Quantitative PCR Update
Wendy Gloffke | Apr 20, 2003 | 9 min read
Courtesy of Applied Biosystems  THE TAQMAN PROCEDURE: Applied Biosystems' TaqMan procedure relies on the 5'-to-3' exonuclease activity of Taq polymerase. The TaqMan probe bears a fluoro-phore at the 5' end and a quencher on the 3' end, rendering the molecule non-fluorescent. During amplification, the probe binds to the template between the two PCR primers. When the polymerase encounters the probe, it starts chewing away at the end, releasing the fluorophore into solution, where it is free

Innovations Expand Lab Power, Uses Of PCR Technique
Ricki Lewis | Jul 25, 1993 | 8 min read
The gene amplification technique invented by genetics researcher Kary Mullis on a moonlit drive through the northern California hills a decade ago--the polymerase chain reaction (PCR)-- continues to revolutionize the life sciences. Uses in molecular biology research and in diagnostic tests are proliferating, and PCR is even bringing a new molecular approach to such fields as paleontology and epidemiology. The following companies are among those supplying PCR-related products for the resear
