• proteins
  • Finally, the cell debris can be removed by centrifugation so that the proteins and other soluble compounds remain in the supernatant. (wikipedia.org)
  • When a vessel (typically a tube or bottle) containing a mixture of proteins or other particulate matter, such as bacterial cells, is rotated at high speeds, the inertia of each particle yields a force in the direction of the particles velocity that is proportional to its mass. (wikipedia.org)
  • The E1, E2, and core structural proteins are required for particle formation ( 5 , 6 ) but not for viral RNA replication or translation ( 7 , 40 ). (pubmedcentralcanada.ca)
  • Zonal profiles of absorbance at 280 mµ, proteins, glycogen, and enzymatic activities (phosphorylase b kinase, phosphorylase b, and glycogen synthetase) were performed. (rupress.org)
  • membrane
  • 5. The process of any one of the claims 1 to 4 wherein after the at least one chromatographic step on porous particles, membrane adsorbers, and monoliths an ultra filtration and/or a sterile filtration is performed. (sumobrain.com)
  • viruses
  • However, cryo-EM single-particle reconstructions in which protein main-chains may be traced reliably or individual side-chains are well resolved have been limited to large icosahedral viruses, and have typically required averaging over millions of asymmetric units ( Grigorieff and Harrison, 2011 ).

  • structural
  • Although electron cryo-microscopy (cryo-EM) single-particle analysis has become an important tool for structural biology of large and flexible macro-molecular assemblies, the technique has not yet reached its full potential. (elifesciences.org)
  • nature
  • However, how many nucleosomes of this nature exist relative to zonal bivalency, and very importantly, what genomic positions these occupy, remains unknown. (biomedcentral.com)
  • remain
  • The greater mass allows the particles to travel through layers with a greater viscosity, while the smaller particles will remain at the top, as they lack the mass to travel through the more viscous layers. (wikipedia.org)
  • sizes
  • 3. The process of claim 1 and/or 2 wherein the porous particles have mean pore sizes of from 20 nm to about 500 nm or even more measured by mercury porosimetry. (sumobrain.com)
  • liquid
  • When suspensions of particles are "spun" in a centrifuge, a "pellet" may form at the bottom of the vessel that is enriched for the most massive particles with low drag in the liquid. (wikipedia.org)
  • order
  • The figure describes the separation of three types of particle: red, green and magenta (density increasing in that order). (els.net)
