  2. Gel electrophoresis of proteins - Wikipedia

    en.wikipedia.org/.../Gel_electrophoresis_of_proteins

    In medicine, protein electrophoresis is a method of analysing the proteins mainly in blood serum. Before the widespread use of gel electrophoresis , protein electrophoresis was performed as free-flow electrophoresis (on paper) or as immunoelectrophoresis.

  3. Gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis

    Electrophoresis is a process that enables the sorting of molecules based on charge, size, or shape. Using an electric field, molecules (such as DNA) can be made to move through a gel made of agarose or polyacrylamide. The electric field consists of a negative charge at one end which pushes the molecules through the gel, and a positive charge at ...

  4. SDS-PAGE - Wikipedia

    en.wikipedia.org/wiki/SDS-PAGE

    Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. 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.

  5. History of electrophoresis - Wikipedia

    en.wikipedia.org/wiki/History_of_electrophoresis

    Since the 1950s, electrophoresis methods have diversified considerably, and new methods and applications are still being developed as affinity electrophoresis, capillary electrophoresis, electroblotting, electrophoretic mobility shift assay, free-flow electrophoresis, isotachophoresis, preparative native PAGE, and pulsed-field gel electrophoresis.

  6. Electrophoresis - Wikipedia

    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

  7. 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.

  8. Polyacrylamide gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Polyacrylamide_gel...

    Picture of an SDS-PAGE. The molecular markers (ladder) are in the left lane. Polyacrylamide gel electrophoresis (PAGE) is a technique widely used in biochemistry, forensic chemistry, genetics, molecular biology and biotechnology to separate biological macromolecules, usually proteins or nucleic acids, according to their electrophoretic mobility.

  9. Polyacrylamide - Wikipedia

    en.wikipedia.org/wiki/Polyacrylamide

    In 1959, the groups of Davis and Ornstein [4] and of Raymond and Weintraub [5] independently published on the use of polyacrylamide gel electrophoresis to separate charged molecules. [5] The technique is widely accepted today, and remains a common protocol in molecular biology labs.
