Gel-Based Isoelectric Focusing And Applications

Gel-based isoelectric focusing (IEF) separates proteins according to their isoelectric points, offering a detailed view of charge differences that other analytical methods may not reveal. Explore the history of IEF, the mechanism behind the separation process, and the theory that explains how a protein’s net charge changes with pH. From these fundamentals, learn how IEF supports key applications such as IgX diagnostics, antibody quality control, and the visualization of post-translational modifications. Connect core scientific principles to practical laboratory use, and gain a clearer understanding of what IEF can reveal about protein identity, purity, and variation.
