Beckman’s Aviv Analytical Ultracentrifuge Fluorescence Detection System (AU-FDS) ProteomeLab XL-A, XL-I analytical ultracentrifuges provide analysis of heterogeneity, stoichiometry, interacting/self-associating systems and molecular conformation. The system measures macromolecules as interacting elements in solution, rather than in isolation, diluted or bound to a substrate.
