Use of the PROTEAN® i12™ IEF System for In-Gel Peptide Fractionation Prior to LC-MS and Comparison with Off-Gel Fractionation

This tech report compares in-gel and off-gel separation of proteins in terms of overall speed and simplicity of the workflow, resolution of the separation, and depth of proteome coverage provided. Results found that as well as higher peptide yields, in-gel separations were better suited to take full advantage of downstream analysis methods.
