Gel Electorphoresis Mobility: Particle Migration

Not what you're looking for?

Ask Custom Question

Electrophoretic mobility, describes the velocity of a particle moving through a gel matrix under the influence of an electrical field. Given a constant electrical field, what characteristics of the molecule influence its velocity through the matrix? State whether these characteristics enhance or diminish the particle's migration through the gel.

  • Affinity Chromatography

    The mobility of the purified protein correlates roughly with the standard protein, indicating that the purified protein is indeed albumin because they migrate as the same size on the gel.

    SDS page relies upon molecules migrating thorough a polyacrylamide gel in response to an electric current.

  • Gel eletrophoresis of sickle cell anemia patient

    The change in amino acid at position six corresponds to an altered migration distance in the gel (because the size has changed).

  • Effect on PAGE gel

    c) Decreasing the voltage at which the gel was run Response: Generally speaking, if we decrease the voltage, the molecules in the matrix (that were loaded in the wells) will migrate slower, although technically, the real issue in slowing down migration

  • Mechanisms of Genetic Recombination in Nature

    Electrophoresis and chromatography both separate molecules by varying the rate of migration. Electrophoresis consists of using the gel or current to vary rate of migration.

  • Specificity of Albumin Binding

    We've got a huge band at the slower (higher up the gel) migration site (lots of BSA-bromophenol blue complex), but now we're starting to see lots of free unbound bromophenol blue migrating faster down the gel.
