مستخلص: Manual spot excision for protein identification from fluorescent stained two-dimensional (2-D) gels is hard to accomplish. Here, we explore the use of ProteomIQ Blue as a post-stain method for the visualization of fluorescent stained/labeled proteins. We show that ProteomIQ Blue post-staining is almost as sensitive as staining with SYPRO Ruby or cyanine dyes alone. More than 90% of the protein spots that are stained with the fluorescent stains are still detectable with ProteomIQ Blue. In protein identification by mass spectrometry, ProteomIQ Blue post-stained spots provide high sensitivity and high protein sequence coverage of the peptide mass maps in both MALDI-TOF−MS and ESI−MS/MS analyses. In conclusion, post-staining of fluorescent stained gels with ProteomIQ Blue provides a facile and a powerful method to achieve quantitative protein analysis as well as protein identification in the same semianalytical gel without requiring sophisticated/expensive robotic equipment.
