Much of modern cell and molecular biology relies on the isolation of pure, functionally intact populations of cells, subcellular organelles and macro-molecules in high yield and both research and clinical applications provide an impetus for the development of improved separation technology.
The most commonly used method of separating suspensions of mixed populations of biological particles is centrifugation in density gradients - and the choice of medium used to form the gradients is critical for the retention of particles function. Since the early sixties Nycomed have been developing and producing iodinated compounds as X-ray imaging agents. It was recognized early on that these compounds were also well suited to the formation of density gradients and offered new opportunities for improved methods of separating biological particles, especially osmotically-sensitive cells and subcellular organelles. Nycomed has therefore been actively involved over the last 30 years in the research and development of density gradient
