  • All other previously known gel phase transitions have occurred as the result of temperature changes and only one previous case documents this type of solvent dependent morphological change. (wikipedia.org)
  • phases
  • A new form of chromatogram employing two liquid phases A theory of chromatography. (wikipedia.org)
  • An aqueous phase containing drug is added to this and the resulting two phases are sonicated at 4-5 °C. The clear gel formed is further sonicated after the addition of a small amount of phosphate buffered saline. (wikipedia.org)
  • The process is similar to paper chromatography with the advantage of faster runs, better separations, and the choice between different stationary phases. (wikipedia.org)
  • However, organic solvents are slightly miscible with water and the characteristics of both phases change making it difficult to obtain pure hydrophobicity scale. (wikipedia.org)
  • Molecules
  • It is an example of a sol-gel process wherein a molecular precursor (typically tetraethylorthosilicate) is first reacted with water in an alcoholic solution, the resulting molecules then joining together to build larger structures. (wikipedia.org)
  • liquid
  • A variety of desalting and affinity-purification supports are available pre-packed in 1mL and 5mL Thermo Scientific Pierce Chromatography Cartridges for processing manually or by automated liquid chromatography (LC) systems. (thermofisher.com)
  • This band was cut out from the gel and digested with trypsin, and peptides from it were separated from one another by reverse phase high performance liquid chromatography. (wikipedia.org)
  • Unlike other gels, it maintains the same consistency throughout its structure and is stable, which means it does not separate into sections of solid mass and those of more liquid mass. (wikipedia.org)
  • density
  • This lets clay particles connect in a chain and allows the gel to form at a low density. (wikipedia.org)
  • Producing a relatively high power for a given weight, the battery could be incorporated into microscope devices if the gel could be made at a low enough density. (wikipedia.org)
  • procedure
  • The high surface area of the coating, characteristic of materials fabricated by the sol-gel process, resulted in capillary columns with a stronger retention than those prepared by a conventional procedure. (springer.com)
  • Once this clue had been obtained, the identification could be confirmed by a less onerous procedure: Overexpression of the putative NAPE-PLD cDNA in COS-7 cells yielded a strong NAPE-PLD enzymatic activity, whose characteristics were shown to be similar to those of the original heart extract. (wikipedia.org)
  • To run a thin layer chromatography plate, the following procedure is carried out: Using a capillary, a small spot of solution containing the sample is applied to a plate, about 1.5 centimeters from the bottom edge. (wikipedia.org)
  • equilibrium
  • The stability of a gel is dependent on the equilibrium between the assembled network and the dissolved gelators. (wikipedia.org)
  • Equilibrium gel is made from a synthetic clay. (wikipedia.org)
  • Equilibrium gel is similar to any gel in the way that it is a colloid in which the disperse phase has combined with the dispersion medium to produce a semisolid material. (wikipedia.org)
  • The difference with equilibrium gel is that it will not separate over time into two separate phase like all other gels. (wikipedia.org)
  • From this observed properties the name equilibrium gel was derived. (wikipedia.org)
  • Equilibrium gel shares the traits of all soft matter. (wikipedia.org)
  • One of the main characteristics of Equilibrium gel as with soft matter is that it displays various mesocopic structures originating from a large number of internal degrees of freedoms of each molecule. (wikipedia.org)
  • Scientists are already coming up with potential applications for equilibrium gel. (wikipedia.org)
  • assay
  • The FDA has approved four variations of the LAL test: gel-clot, turbidimetric, colorimetric, and chromogenic assay. (wikipedia.org)
  • known
  • Unlike the lower concentrations where the arrangement of clay particles was continually in flux, the particles above 1% concentration locked into a stable structure which is known as equilbrium gel. (wikipedia.org)
  • properties

  • Scanning Electron Microscopy is a useful means for researchers to determine the structural properties of a low molecular-mass weight gel. (wikipedia.org)
  • The non-ionic surfactant is burned away to produce empty pores, increasing the surface area and altering the surface characteristics of the resulting particles, allowing for much greater control over the physical properties of the material. (wikipedia.org)
  • thin
  • Measurement of the enzyme activity was done by thin layer chromatography of a radioactive substrate sensitive to the NAPE-PLD enzymatic activity: Cleavage of the substrate affected where it appeared on the plate when the radiation was detected on a bioimaging analyzer. (wikipedia.org)
  • particles
  • Clay particles interact in an anisotropic way differing from the typical isotropic way of colloidal particles, which normally interact with all of their nearest neighbors when forming a gel. (wikipedia.org)
  • form
