    2010-12-4 · The polyacrylamide gels may be cast as i fixed concentration gel (e.g. 10%) or as a gradient gel (e.g. 7-15 %). There is also a choice between continuous and discontinuous buffer systems. If the same buffer ions are present throughout sample, gel and electrophoresis buffer the electrophoresis is referred to as continuous buffer PAGE.

  • SDS-PAGE

    SDS-PAGE. Polyacrylamide Gel Electrophoresis (PAGE) is one of the most widely used laboratory methods to separate biological macromolecules, such as proteins and nucleic acids. Macromolecules will be differentiated according to their electrophoresis mobility, which is a function of the length, conformation, and charge of the molecule.

    2014-6-10 · Gel electrophoresis is a broad subject encompassing many different techniques. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) is the most commonly practiced gel electrophoresis technique used for proteins. The method provides an easy way to estimate the number of polypeptides in a sample and thus assess

  • Denaturing gradient gel electrophoresis (DGGE): A

    Denaturing gradient gel electrophoresis (DGGE) can theoretically detect single base mutations in DNA [1-3]. Amplicons of the same length but with different nucleotide compositions are separated in a denaturing gradient gel of polyacrylamide, based on their differential denaturation profile. During denaturation, the two strands of a DNA molecule ...
