WebThe combination of pore size and protein charge, size, and shape determines the migration rate of the protein. In this unit, the standard Laemmli method is described for discontinuous gel electrophoresis under denaturing conditions, that is, in the presence of sodium dodecyl sulfate (SDS). Both full-size and minigel formats are detailed. WebDisc gel electrophoresis on native polyacrylamide slab gels (12% or 15% acrylamide) is performed without SDS using the discontinuous buffer system according to Laemmli. …
