Analysis of Complex Protein Mixtures Using Multidimensional Protein Identification Technology (MuDPIT)

from the sample is critical, because salt prevents the peptides from binding to the strong cation-exchange portion of the 2D column. A sample containing 1 M salt will fail in a MuDPIT analysis. In addition, the extraction cartridge concentrates

Polyacrylamide gel electrophoresis is a widely used technique to separate proteins from biological samples.Moreover,the development of two-dimensional (2D)gel electrophoresis has provided a tool for differential protein display,which allows
