  2. Gel electrophoresis of proteins - Wikipedia

    en.wikipedia.org/.../Gel_electrophoresis_of_proteins

    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.

  3. Electroblotting - Wikipedia

    en.wikipedia.org/wiki/Electroblotting

    Typically the electrophoresis gel is stained with Coomassie brilliant blue following the transfer to ensure that a sufficient quantity of material has been transferred. Because the proteins may retain or regain part of their structure during blotting they may react with specific antibodies giving rise to the term immunoblotting .

  4. Temperature gradient gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Temperature_gradient_gel...

    The same equipment can be used for analysis of protein, which was first done by Thomas E. Creighton of the MRC Laboratory of Molecular Biology, Cambridge, England. [4] Similar looking patterns are produced by proteins and nucleic acids, but the fundamental principles are quite different.

  5. Western blot - Wikipedia

    en.wikipedia.org/wiki/Western_blot

    The western blot method is composed of gel electrophoresis to separate native proteins by 3-D structure or denatured proteins by the length of the polypeptide, followed by an electrophoretic transfer onto a membrane (mostly PVDF or nitrocellulose) and an immunostaining procedure to visualize a certain protein on the blot membrane.

  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. Gel doc - Wikipedia

    en.wikipedia.org/wiki/Gel_doc

    An example Gel documentation system, showing the results of gel electrophoresis on a connected monitor.. A gel doc, also known as a gel documentation system, gel image system or gel imager, refers to equipment widely used in molecular biology laboratories for the imaging and documentation of nucleic acid and protein suspended within polyacrylamide or agarose gels.

  8. Difference gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Difference_gel_electrophoresis

    Difference gel electrophoresis (DIGE) is a form of gel electrophoresis where up to three different protein samples can be labeled with size-matched, charge-matched spectrally resolvable fluorescent dyes (for example Cy3, Cy5, Cy2) prior to two dimensional gel electrophoresis.

  9. Protein methods - Wikipedia

    en.wikipedia.org/wiki/Protein_methods

    Protein immunoprecipitation: technique of precipitating a protein antigen out of solution using an antibody that specifically binds to that particular protein. Immunoelectrophoresis : separation and characterization of proteins based on electrophoresis and reaction with antibodies.
