title: Size-exclusion chromatography with on-line light scattering.
abstract: This unit describes the use of size-exclusion chromatography with on-line light scattering, UV absorbance, and refractive index detectors (SEC-LS/UV/RI) to determine: (a) the molecular weight of simple proteins containing no carbohydrates, (b) the molecular weight of glycoproteins, and (c), most importantly, the molecular weight and stoichiometry of protein-protein complexes or protein-carbohydrate complexes. Multiangle light scattering is also discussed.
