  2. Electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Electrophoresis

    Electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field. As a rule, these are zwitterions .

  3. Gel electrophoresis of proteins - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis_of...

    Proteins separated by SDS-PAGE, Coomassie brilliant blue staining. Protein electrophoresis is a method for analysing the proteins in a fluid or an extract. The electrophoresis may be performed with a small volume of sample in a number of alternative ways with or without a supporting medium, namely agarose or polyacrylamide.

  4. Gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis

    Agarose gels do not have a uniform pore size, but are optimal for electrophoresis of proteins that are larger than 200 kDa. [10] Agarose gel electrophoresis can also be used for the separation of DNA fragments ranging from 50 base pair to several megabases (millions of bases), [11] the largest of which require specialized apparatus. The ...

  5. Agarose gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Agarose_gel_electrophoresis

    Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar.

  6. SDS-PAGE - Wikipedia

    en.wikipedia.org/wiki/SDS-PAGE

    SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.

  7. Molecular-weight size marker - Wikipedia

    en.wikipedia.org/wiki/Molecular-weight_size_marker

    The purpose of gel electrophoresis is to separate proteins by physical or chemical properties, which include charge, molecular size, and pH.< When separating based on size, the ideal method is SDS-PAGE or polyacrylamide gel electrophoresis and molecular-weight size markers are the appropriate standards to use. Gels can vary in size.

  8. Hemoglobin electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_electrophoresis

    The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis.After the sample has been treated to release the hemoglobin from the red cells, it is introduced into a porous gel (usually made of agarose or cellulose acetate) and subjected to an electrical field, most commonly in an alkaline medium.

  9. Two-dimensional gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_gel...

    Two-dimensional gel electrophoresis, abbreviated as 2-DE or 2-D electrophoresis, is a form of gel electrophoresis commonly used to analyze proteins. Mixtures of proteins are separated by two properties in two dimensions on 2D gels. 2-DE was first independently introduced by O'Farrell [ 1 ] and Klose [ 2 ] in 1975.
