DELETION BY DESIGN:Courtesy of Guci GiaeverThe deletion cassette module used to delete each yeast gene contains two 74-basepair tags upstream and downstream (UPTAG and DNTAG) of the KanMX gene, which confers resistance to the drug geneticin. UPTAG and DNTAG contain 18 basepairs of genomic sequence to flank the yeast's open reading frame, and U1 and U2, or D1 and D2 PCR primers for amplifying a unique 20-basepair TAG region-the so-called molecular barcode. A second round of PCR adds 45 base-pairs

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

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.
