Beckman Coulter, Inc. and Aviv Biomedical, Inc. announced an agreement authorizing Aviv to sell and install its Fluorescence Detection System on fielded Beckman Coulter ProteomeLab XL-A, XL-I analytical ultracentrifuges. The ProteomeLab XL-A, XL-I provides analysis of heterogeneity, stoichiometry, interacting/self-associating systems and molecular conformation. The system measures proteins and other macromolecules as interacting elements in solution (rather than in isolation, diluted, or bound to a substrate). The Aviv Analytical Ultracentrifuge Fluorescence Detection System (AU-FDS) offers a complementary approach to measuring molecular interaction and aggregation behavior.

The fluorescent labeling of a single component in a mixture enables investigators to validate drug lead efficacy by confirming that it only binds to the desired substrate. With the new AU-FDS accessory, the XL-A, XL-I’s core absorbance/interference detection can be run sequentially with the fluorescence optical system. In addition to rigorous characterization, this technology measures relative changes in the distribution of molecular weights.
