    How Isoelectric Focusing Works

    Yes, IEF can be combined with other separation techniques, such as gel electrophoresis and chromatography, to enhance protein analysis and separation.

    Isoelectric focusing is a technique that separates proteins based on their isoelectric point (pI), which is the pH at which a protein has no net charge. In IEF, proteins are focused onto a gel matrix, and an electric field is applied to drive the separation of proteins. The gel matrix is coated with a pH gradient, allowing proteins to migrate to their respective pI. This process results in a sharp and distinct separation of proteins, providing a clear and accurate representation of the protein mixture.

    What is the Isoelectric Point (pI)?

  • Improved protein analysis: IEF provides more accurate and reliable protein analysis, enabling the development of new therapies and vaccines.
