#112 — Isoelectric focusing (IEF) is a powerful technique distinct from the more familiar SDS-PAGE, [1,2] tailored for separating proteins or peptides based on their isoelectric points (pI). [3]
This method capitalizes on the migration of charged molecules through a stable pH gradient until they reach a zone where their net charge is zero, halting their movement.
Essential to setting up an IEF experiment are the IPG strips, equipped with a pH-responsive gel, and the sample, often mixed with carrier ampholytes for efficient migration.
IEF's utility spans various applications, from enhancing 2D-PAGE protein separations to analyzing post-translational modifications and preparing samples for mass spectrometry. [4]
