Protein charge determination – How to?

One of the advanced features in the Zetasizer Nano software is protein charge determination. In order to take advantage of the calculator, both size Dynamic Light Scattering (DLS) and electrophoretic mobility (zeta, ELS) data combine. In this post, we show…READ MORE >
