ERK1/2 ACTIVATIONCourtesy of Biosource Internationalis plainly visible in heart tissue from an MHC-Rac1 transgenic mouse (right), compared with its normal counterpart (left). Green, pERK 1/2 (pTEpY185/187); blue, actin; red, nuclei.Protein phosphorylation is one of the most widely studied posttranslational modifications, with good reason. Many cellular signaling events rely on the addition or subtraction of phosphate groups (by kinases and phosphatases, respectively) to serine, threonine, and ty

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

In tomorrow's (July 1) issue of Genes & Development, Siu Sylvia Lee, of the department of molecular biology and genetics at Cornell University in Ithaca, NY, and Gary Ruvkun, of the department of genetics at Harvard Medical School, report ?the first genome-wide functional genomic screen for longevity genes.? The two teams used a library of 16,475 RNA interference constructs (created by Julie Ahringer at the University of Cambridge, UK) to inactivate genes in the nematode, Caenorhabditis eleg

Click to view the PDF file: Bead-based Fluorescent Multiplex Protein Analysis Systems Courtesy of LINCO ResearchLabMAP-based systems use internally dyed fluorescent microspheres to analyze as many as 100 different analytes concurrently. Today's competitive, high-paced research environment has stimulated the development of a host of approaches for rapid, cost-efficient analyses of large numbers of samples. In keeping with this trend, methods for simultaneously analyzing multiple species in a g

Courtesy of BD Biosciences Pharmingen  COLOR CODING: Multiplexed bead-based assays, like BD Biosciences' Cytometric Bead Array (shown), test for multiple analytes in a single vial. The key is in the colors: one hue indicates the bead ID, and the intensity of the second, how much protein has been captured. In today's fast-paced research environment, technologies for speedy, cost-efficient analyses reign supreme. As part of this general trend, techniques for multiplexing, that is, simultan

Ned Shaw Margaret Atwood's novel Oryx and Crake describes a gruesome future for organ transplantation: Pigoons, genetically altered pigs that grow surplus human organs. Though this scenario may never come to pass, it is easy to see why the science of human replacement parts ignites the dystopian imagination: It was not too long ago that Charles Vacanti of the University of Massachusetts and coworkers injected a polymer scaffold seeded with cartilage cells into the back of the mouse and created
