PCR Primed To Spur Chain Of Applications
Holly Ahern | Jun 25, 1995 | 10+ min read
What would you do if your research interests revolved around obtaining DNA from a bacterium preserved for millions of years in the gut of a bee stuck in amber, matching up a murderer to crime- scene blood half a century old, or cloning genes from a 1,000- year-old mummy? Most scientists would first consider PCR--the polymerase chain reaction--as a technique for approaching problems such as these. With PCR, minute quantities of nucleic acids can be amplified millions of times into sufficient qua
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
'Limitless' PCR Technology Offers Scientists Vast Variety Of Applications
Holly Ahern | Feb 4, 1996 | 10 min read
With the introduction of the polymerase chain reaction by Nobelist Kary Mullis and other scientists with the former Cetus Corp. in 1985, researchers can amplify their minute samples into a virtually unlimited supply of material to study.
A New Symbiosis For MD's And Scientists

Advances in molecular biology foster greater interdependency among physicians, researchers The province of the scientist traditionally has been one of theory and experiment, exploration and discovery--contrasting sharply with the practical concerns of the physician. But times have changed. Today, physicians find themselves in need of knowledge in such esoteric matters as the polymerase chain reaction and restriction fragment-length polymorphism maps. Meanwhile, scientists are having to acqua
Convenient, Performance-Boosting Products Put PCR On The Fast Track
Holly Ahern | May 26, 1996 | 10 min read
PCR On The Fast Track The polymerase chain reaction (PCR) revolutionized researchers' ability to manipulate DNA and RNA. With PCR-an amplification procedure that mimics DNA replication-molecular biologists no longer have to painstakingly purify large quantities of DNA for genetic experiments. The growing number of plastics and laboratory disposables, combined with the advent of reagent kits designed expressly for PCR, are making it easier for scientists to apply the technology in new areas.

Laser Microdissection Systems
Emily Willingham | May 12, 2002 | 9 min read
Years ago, tissue samples mounted on glass slides were consigned to a future of histological or immunohistological examination, and then, to the trash bin. Postmicroscopic polymerase chain reaction (PCR) analyses of interesting cellular colonies were impossible, because there was no way to get those cells off the slides, or to isolate those few cells from the vast majority of uninteresting ones. But thanks to laser microdissection (LMD), that is no longer the case. LMD allows researchers to targ
