Working in a Virtual Laboratory
Jennifer Fisher Wilson | Dec 6, 1998 | 6 min read
NEXT STEP: The virtual center "is the natural evolution of our shared research interests," says Ashley T. Haase, chair of the microbiology department at the University of Minnesota. When AIDS researchers physically located in four different states hold a meeting, it almost feels like they're sitting at a table across from each other--but they're really just facing their individual computer screens. They view slides of the human immunodeficiency virus in lymphoid tissue in real time and discuss

Prospecting for Gold in Genome Gulch
Amy Adams | Apr 14, 2002 | 9 min read
The human genome is much like the American West of the 1850s: Everyone wants a piece of the pie. Similar to gold prospectors of 150 years ago, biotech and pharmaceutical companies, and even universities, are frantically searching for the nuggets of gold that will help them find the mother lode—a gene whose function is sufficiently marketable to make all of the preliminary research worthwhile. Companies that do strike gold get to introduce new classes of drugs to the market. Others hope to

Comparative Genomics Reveals The Interrelatedness Of Life
Ricki Lewis | Jan 4, 1998 | 7 min read
Photo: Karen Young Kreeger EXCITING ERA: TIGR's Craig Venter says efforts to unravel the information being gathered will last "into the next century." While the list of genome projects grows, research focus is shifting from structure to function. So even as automated DNA sequencers crank out bases and powerful software overlaps pieces of genomes (contigs) to establish gene orders, investigators are searching and comparing those sequences among species, an approach called comparative genomics.

One Step Beyond: Going Beyond Genomics With Proteomics And Two-Dimensional Gel Technology
Laura Defrancesco | Jan 3, 1999 | 10+ min read
Proteomes and 2D Gel Apparatus Providers Big science has moved on to proteins. With the new brand of science termed proteomics--named by the Australians Marc Wilkins and Keith Williams to mean the "set of PROTEins encoded by the genOME"--the push is on around the globe to produce a complete description of a cell/tissue/organism in terms of the proteins produced. The challenge is all the greater because the expressed protein pattern changes with time and environment--responding to developmenta
The Divine Cytokine

Tools for Cytokine Research Companies producing cytokines Courtesy of Alexis CorpCytokine Network Many proteins and peptides affect the growth, identity, and function of eukaryotic cells. Very often their effects are highly pleiotropic, making exact boundaries and distinctions between proteins such as hormones, growth factors, and cytokines difficult to pin down. The result is a nomenclature tangle almost as complex as the regulatory circuits these molecules mediate. Although this treatment of
