One of the most widely used water-soluble polymers is Polyvinylpyrrolidone (PVP). For more than 70 years it is applied in a variety of applications in medicine, pharmacy, cosmetics and industrial production. PVP binds to polar molecules exceptionally well. It supports the solubility of tablets in water, makes the glue stick adhesive and plays an essential role in the production of membranes. In ceramic, paper and dye applications, it produces visual effects such as gloss and brilliancy. As a food additive, PVP is a stabilizer (E1201). A characteristic feature of a certain polymer is its molecular weight distribution curve, which is usually obtained by SEC Analysis more
The ESI-TOF mass spectrometers micrOTOF and micrOTOF focus do not only provide accurate mass measurements but additionally describe the True Isotopic Pattern TIPTM. For molecular formula generation this unique combination significantly reduces the number of possible formula candidates and the elemental composition of compounds with molecular weights far higher than 500 Da can unequivocally be determined more
Twsett originated the chromatography with his work about the separation of chlorophyll in 1903. For some time it was relatively quite around this new technology. Exceptions were the workings of Kuhn and Lederer (1931) as well as of Hesse (1936 and 1942). A break through succeeded to E. Cremer during the 40ies, but hardly considered caused by the war events, what however in the years 1950/51 by the conception of the gas chromatography suddenly changed and involved a rapid development more
Abstract The peptidoglycan (PG) cell wall is a unique macromolecule responsible for both shape determination and cellular integrity under osmotic stress in virtually all bacteria. A quantitative understanding of the relationships between PG architecture, morphogenesis, immune system activation, more
Abstract During the past decade several peptides containing RGD sequence have been conjugated with different chelating agents for labeling with various radionuclides for the diagnosis of tumor development.
