  • April 22, 2021 -- A new cell-free synthetic biology technique that increases the volume of membrane components in the manufacture of conjugate vaccines can significantly improve the efficiency of vaccine production, according to a new method published in Nature Communications on April 22. (scienceboard.net)
  • The researchers therefore developed a new manufacturing platform -- called in vitro conjugate vaccine expression (iVAX) -- that uses cell-free synthetic biology, a process in which researchers remove a cell's outer wall (or membrane) and repurpose its internal machinery. (scienceboard.net)
  • The team developed a method that enhances membrane-dependent functions of cell-derived vesicles in CFE systems. (scienceboard.net)
  • Membrane structures are present in all CFE systems, as vesicles formed by fragmentation and rearrangement of cell membranes during cell lysis and extract preparation. (scienceboard.net)
  • By learning how to use membrane proteins effectively, we can really advance cell-free systems. (scienceboard.net)
  • Its work finished, the tube disassembles, resealing the punctured cell membrane as it disappears. (asmblog.org)
  • Taken together, our study identifies a novel form of STP which may provide the basis for both short- and long-term potentiation, in the absence of any protein synthesis-dependent steps, and involve CaMKII activity exclusively in the presynaptic cell. (nartsignaling.com)
  • Many protein bands were identified in the K. pneumoniae OMVs, but the protein profiles were different between OMVs and whole-cell lysates (Fig. 1b), find more suggesting the absence of bacterial contaminants. (nartsignaling.com)
