Since its inception in the early 1990's, the Protein Solutions DynaPro dynamic light scattering instrument began appearing in protein crystallization and characterization labs throughout the world - the first DLS (Dynamic Light Scattering) technology meeting the scientific community's need to measure small volumes of proteins under very dilute solution conditions. The DynaPro quickly earned acceptance on a global basis, and has since become an indispensable tool for biomolecular sizing and characterization. The great success of the DynaPro DLS technology is attributed to the on-going evolution in performance and capabilities designed to meet customer requirements, and is reflected by the enormous number of peer-reviewed publications citing the DynaPro.
