  • isolate
  • This standardized variant of native gel electrophoresis is used by biologists to isolate active or native metalloproteins in biological samples and to resolve properly and improperly folded metal cofactor-containing proteins or protein isoforms in complex protein mixtures. (wikipedia.org)
  • electrophoresis
  • Density gradient ultracentrifugation (DGUC) and gel electrophoresis are conventionally used to obtain lipoprotein profiles of animals. (go.jp)
  • In gel electrophoresis proteins are normally separated by charge, size, or shape. (wikipedia.org)
  • Due to the specific properties of the prepared gel and electrophoresis buffer solution (which is basic and contains Tris-HCl and NaN3), most proteins of a biological system (e.g. (wikipedia.org)
  • form
  • For example, it is impossible to separate the constituents of azeotropic liquids or solutes which form isomorphic crystals by distillation or recrystallization but such separations can be achieved using membrane technology. (wikipedia.org)
  • However, techniques such as gel permeation chromatography, X-ray crystallography and 27Al-NMR have been used in research by various groups including that of Nazar and Laden to show that the material is based on Al13 units with a Keggin ion structure and that this base unit then undergoes complex transformations to form larger poly-aluminium complexes.

  • sample
  • 2.3 by-pass or loop injector-the injector most common in liquid exclusion chromatography and which utilizes a sample chamber that can be filled with sample while it is temporarily external to the flowing liquid stream. (scribd.com)
  • This new liquidliquid extraction method comprises the addition of sodium hydroxide to the tissue sample followed by extraction with ethyl acetate. (scinapse.io)
  • terms
  • Limited studies comparing these report that in terms of bioavailability liquid SMEDDS are superior to solid SMEDDS, which are superior to conventional tablets. (wikipedia.org)
  • medium
  • Gels consist of a solid three-dimensional network that spans the volume of a liquid medium and ensnares it through surface tension effects. (wikipedia.org)
  • physical
  • This internal network structure may result from physical bonds (physical gels) or chemical bonds (chemical gels), as well as crystallites or other junctions that remain intact within the extending fluid. (wikipedia.org)
