  • proteins
  • The stationary phase has certain physical and chemical characteristics that allow it to interact in various ways with different proteins. (slideplayer.com)
  • Thus, they exposed columns from different silica and bonding lots to a series of repetitive injections of standard proteins using mobile phase conditions that are typical for the quality control analysis of monoclonal antibodies. (sigmaaldrich.com)
  • Protein separation techniques including SCX, Offgel IEF and 1d-gel electrophoresis, in conjunction with LC-MS (with the precursor 359 scan), were applied to microsome prep samples in order to identify modified proteins. (gla.ac.uk)
  • A print out of the image was used as a map for the excision of modified proteins from a duplicate gel. (gla.ac.uk)
  • In Top-down proteomics, researchers can feed intact full proteins directly into mass spectrometers, and are able to capture the distinct characteristics of each one-of-a-kind proteoform. (wikipedia.org)
  • precursor
  • This data was used to create a precursor ion scan specific for the presence of this characteristic ion. (gla.ac.uk)
  • According to historical analysis of L. S. Ettre, however, Runge's work had "nothing to do with chromatography" (and instead should be considered a precursor of chemical spot tests such as the Schiff test). (wikipedia.org)
  • sodium silicate
  • Precipitated silica is derived from the reaction of sodium silicate, an alkaline liquid silicate known as waterglass, with an acid to form porous silica aggregates that are usually washed, dried, and milled to a final product. (mrs.org)
