Perfusate pH Changes from Acidic to Alkaline Triggering Conformational Change in BSA - A Video by Farfield Group

This video shows Bovine Serum Albumin (BSA) molecules binding to BS3 molecules adhering to the surface of an optical chip. The BSA molecules then undergo a conformational change as the pH of the perfusate changes from acid to alkaline. This is an excerpt from a video that iemedia solutions produced for the Scientific Instrumentation Division of the Farfield Group to illustrate the measurement capabilities of their Dual Polarisation Interferometry technology.
