Today, researchers have announced the development of a new method for the purification of proteins used in drug production. This new method promises to make the process of purifying such proteins significantly cheaper and more efficient. The technique uses a special type of ion exchange chromatography to separate proteins from other molecules, leaving the proteins suitable for use in drug production. This new method could potentially reduce the cost of production for a variety of drugs and make them more readily available to those in need.
