  The MALS-RI device is designed to determine the degree of self-association of molecules. That is, it can detect whether the molecule is monomeric, dimeric, trimeric, or larger. This information is vitally important to understand the function of biological macromolecules. The device uses Multiple Angle Light Scattering to determine self-association independent of molecular shape. This is useful as the oblong shape of some biological molecules makes assessment of self-association state problematic via normal light scattering methods. The RI is refractive index: this part of the unit accurately measures the concentration of the molecule in question. The concentration is required for the MALS analysis. The entire unit is designed to be placed in series with size exclusion chromatography system (such as the Superdex columns which I have purchased utilizing ETF), so that proteins are first separated by size (this may separate monomers from dimers of the same protein for instance) and then the self-association state of each peak eluting from the column is determined separately by the MALS-RI.
