Measuring protein isoelectric points by AFM-based force spectroscopy using trace amounts of sample

The isoelectric point (pI) is an intrinsic property of surfaces and molecules, and is defined as the pH value at which the entity carries zero net electrical charge 1. The pI is particularly important ...
