Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod

Date: November 9, 1998Baculovirus Expression Vectors In the recent past, efforts to elucidate the relationship between protein structure and biological function have intensified. Of particular interest is an understanding of the elements of sequence and structure that mediate specific functions. Often the protein of interest is in low abundance in its natural source and can be difficult to purify and/or unstable--subject to proteolytic cleavage or unfolding/non specific refolding during exhaust
Epigenetics: Genome, Meet Your Environment

©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat

Large Fragment Cloning Products and Services Gone are the days when all you had to do to get out of grad school was identify and clone a new gene. Besides, with the information rapidly gathered through the Human Genome Project, there will soon no longer be a "new gene." Enormous projects such as sequencing entire genomes have created a need to play with bigger pieces of the puzzle, and a new universe of technologies adapted to large DNA fragments has appeared. Assignment of a new gene to a par

By The Scientist Staff Top Ten Innovations 2010 Innovative products that have the life science community buzzing. As the global economy continues to pull out of its recent precipitous nosedive, one mantra rings true from Beijing to Boston—innovation can save us. If developing interesting new technologies and products really is the lifeblood of economic health, then the life sciences industry is innovation’s beating heart. The Scientist rec
