Using the new PROTEAN® i12™ IEF System to Achieve Highly Reproducible Data and Extended Separation Over Multiple pH Ranges in a Single Run

2-D electrophoresis is a multistep technique that separates proteins first by a protein’s isoelectric point and then by its molecular weight. This powerful technique can separate thousands of proteins in a complex proteome and is useful for applications such as protein profiling and biomarker discovery. The drawback of the technique is that it requires multiple steps, each of which can be time-consuming and can contribute to problems with reproducibility.

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.
