Nonradioactive Kinase Assay Kits Safety concerns and economic considerations have fueled a growing trend in the biomedical sciences: to shun the use of radioactivity when practical. Nonradioactive options for numerous applications have become widely available, including a number of nonradioactive kinase assay kits. Assays from different manufacturers employ a wide range of strategies. Most of these kits utilize antibodies, but two nonimmunochemical approaches use fluorescently tagged substrates

Cynical Science and Stem Cells

So powerful has the language of science become that it has in effect been hijacked by those who seek to discredit or even derail it. Two cases in point: Creationists are repackaging their message as the pseudo-science of "intelligent design theory." And pro-life groups are misusing real science, remarkable advances with adult stem cells, to argue that there is no need for embryonic stem cell research--research that carries with it virtually limitless potential for the alleviation of human suffer
Mafia Wars

FIGURE 1:Courtesy of Kendra RumbaughEukaryotic and prokaryotic signaling molecules have similar functions. Mammalian steroid hormones bind to cognate nuclear hormone receptors; Pseudomonas aeruginosa autoinducer N-3-oxododecanoyl homoserine lactone acts as a ligand for the transcriptional activator LasR and is essential for cell-to-cell communication resulting in biofilm formation.Mammals possess sophisticated endocrine networks in which hormonal signals modulate hundreds of biological effects s

Courtesy of Large Scale Biology Agricultural researchers have designed a wide variety of genetically modified plants with traits deemed beneficial to those who grow, market, and consume them. But plants have another role in biotech: Members of the green kingdom also can be used--quite literally-- as manufacturing plants for large-scale, recombinant protein production.1-4 Think GM crops, with a twist. Such proteins have potential industrial, research, and clinical applications. Plant expressi
