Use of "submarine" gel electrophoresis for running multiple two-dimensional protein gels.
An apparatus commonly used for the electrophoresis of submerged agarose gels was used to separate proteins in the second dimension, after isoelectric focusing in the first dimension. Multiple second-dimension gels were stacked one above the other and run horizontally, submerged in the sodium dodecyl sulfate-containing Laemmli buffer system. The reproducibility of the gels run under these conditions is remarkable and eliminates the need for individual vertical electrophoresis units for routine analysis. The units for submerged horizontal gel electrophoresis are easily made or are inexpensively available commercially.
