Several forms of PAGE exist and can provide uncommon types of in rank in this area the protein(s). Nondenaturing PAGE furthermore called native PAGE, separates proteins according to their mass-charge ratio. Denaturing and sinking SDS-PAGE, the generally widely used electrophoresis practice, separates proteins primarily by bulk. Two-dimensional (2D) PAGE separates proteins by isoelectric top in the initially dimenstion and by bulk in the following direction.

SDS-PAGE separates proteins primarily by bulk since the ionic detergent sodium dodecyl sulfate (SDS) denatures and binds to proteins to get on to them evenly with a denial charged. Thus, as a current is useful, all SDS-bound proteins in a sample will migrate through the gel headed for the positively charged electrode. Proteins with a reduced amount of bulk travel more quickly through the gel than persons with greater bulk since of the sieving effect of the gel matrix.

Once separated by electrophoresis, proteins can be detected in a gel with various stains, transferred on a crust pro detection by Western blotting and/or excised and extracted pro analysis by bulk spectrometry. Protein gel electrophoresis is, therefore, a ordinary step in many kinds of proteomics analysis.
