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

Luminescence Developments Help Scientists See The Light
James Kling | May 11, 1997 | 9 min read
Biologists are constantly seeking more sensitive assays to detect the presence of organisms or telltale DNA, RNA, and proteins. Although radioactive tags incorporated into the target itself (or into a complementary strand)-and later detected by Geiger counters or film exposures-have traditionally given good sensitivity, the problems of waste disposal and laboratory monitoring have driven a search for alternative tags that have radioactivity's sensitivity but avoid its hazards. Fluorescent tags-
