Everyone knows that the first genome sequencing projects took years of work and represent the combined product of tens of thousands of individual fragments.

The power of a synchrotron facility can now be found in a laboratory X-ray source.

In the largest project of its kind, Swedish scientists are studying normal and cancerous tissues to discover not only the location and abundance of all human proteins, but also how these are affected by disease states.

newly released confocal microscope, the Eclipse C1-Plus, sports a range of new features, including new adjustable lasers, according to Jeff Larson, Nikon's US product manager for confocal microscopes.

BioSim, from Kansas City, Mo.-based Sceptor Industries https://www.sceptorindustries.com, replaces the need for live bacteria to test the efficiency of pathogen-detection systems.Designed to test PCR-based systems, the device sprays puffs of tiny polystyrene beads coupled to bacterial DNA. The carrier beads simulate bacterial spores in the air and on surfaces, so

Now 3D Molecular Designs https://www.moleculardesigns.com of Wauwatosa, Wis., hopes to make the field truly three-dimensional, allowing new insights into known structures and giving hope to those not blessed with the space-manipulation skills needed to make sense of flat

Courtesy of TrimGenIf you are not lucky enough to have a restriction enzyme site in your mutation-of-interest, chances are you have had to fall back on sequencing to detect it. But this time-consuming method of detecting mutations could soon be a thing of the past, thanks to new technology called Mutector from Sparks, Md.-based TrimGen https://www.trimgen.com.According to marketing manager Brad Oswald, Mutector eliminates false positives and negatives and produces results in 2–3 hours, comp
