  2. Electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Electrophoresis

    2. Illustration of electrophoresis retardation. 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. [1] Electrophoresis is used in laboratories to separate macromolecules based on their

  3. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    Electrophoresis, separates organic molecules based on their different interaction with a gel under an electric potential (i.e., different travel) Capillary electrophoresis; Electrostatic separation, works on the principle of corona discharge, where two plates are placed close together and high voltage is applied. This high voltage is used to ...

  4. Gel electrophoresis of nucleic acids - Wikipedia

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

    Gel electrophoresis of nucleic acids is an analytical technique to separate DNA or RNA fragments by size and reactivity. Nucleic acid molecules are placed on a gel , where an electric field induces the nucleic acids (which are negatively charged due to their sugar- phosphate backbone) to migrate toward the positively charged anode .

  5. Protein purification - Wikipedia

    en.wikipedia.org/wiki/Protein_purification

    Gel electrophoresis is a common laboratory technique that can be used both as preparative and analytical method. The principle of electrophoresis relies on the movement of a charged ion in an electric field. In practice, the proteins are denatured in a solution containing a detergent . In these conditions, the proteins are unfolded and coated ...

  6. Gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis

    Proteins are separated by the charge in agarose because the pores of the gel are too large to sieve proteins. Gel electrophoresis can also be used for the separation of nanoparticles. Gel electrophoresis uses a gel as an anticonvective medium or sieving medium during electrophoresis, the movement of a charged particle in an electric current.

  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.

    This word refers to a doctrine, belief or set of principles that political or religious officials expect others to follow (without question). OK, that's it for hints—I don't want to totally give ...

  9. Gel electrophoresis of proteins - Wikipedia

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

    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 .
