• GST Fusion Proteins

  
  Bench Marks — Authority: 111
  Glutathione-S-transferase (GST) fusion proteins are used in a wide variety of applications in the lab. GST was originally selected as a fusion moiety because it’s not sequestered in inclusion bodies when expressed in bacteria and it can be affinity-purified without denaturation. Purification is fairly ...

• Far From a Lab? Turn a Cellphone Into a Microscope

  
  Innovation Toronto — Authority: 438
  Image via Wikipedia MICROSCOPES are invaluable tools to identify blood and other cells when screening for diseases like anemia, tuberculosis and malaria. But they are also bulky and expensive. Now an engineer, using software that he developed and about $10 worth of off-the-shelf hardware, has adapted cellphones ...

• Slimming gene regulates body fat

  
  Biology News Net — Authority: 138
  Scientists at the University of Bonn have discovered a previously unknown fruit fly gene that controls the metabolism of fat. Larvae in which this gene is defective lose their entire fat reserves. Therefore the researchers called the gene schlank (German for slim). Mammals carry a group of genes that are structurally ...

• Placental precursor stem cells require testosterone-free environment to survive

  
  Biology News Net — Authority: 138
  Trophoblast stem cells (TSCs), cells found in the layer of peripheral embryonic stem cells from which the placenta is formed, are thought to exhibit "immune privilege" that aids cell survivability and is potentially beneficial for cell and gene therapies. Further, the survivability of TSCs has been thought to require ...
