Figure 1From: Immobilized pH gradient-driven paper-based IEF: a new method for fractionating complex peptide mixtures before MS analysisStandardization of a mini SDS-PAGE gel system capable of resolving Cy3-labeled known and synthetic peptides, loaded in increasing amounts. Lanes 1-4: angiotensin. Lanes 5-8: bradykinin. Lanes 9-11: synthetic peptide 72109. Lanes 12-15: synthetic peptide 72120.Back to article page
