Density Gradient Media

Know what you need?

Using Centrifugation

Much of modern cell and molecular biology relies on the isolation of pure, functionally intact populations of cells, subcellular organelles and macromolecules in high yield and both research and clinical applications provide an impetus for the development of improved separation technology. The media are used in density gradient separation for the purification not only of cells and organelles but also membrane vesicles, viruses, proteins, nucleic acids and lipoproteins.

Our density gradient media developed by Serumwerk Bernburg AG are:

Proven to be non-toxic,
Have a low osmolality
Are sufficiently dense to permit the purification of all types of biological particles
In compliance with FDA and EU cGMP standards and regulatory requirements.

OptiPrep™ - Iodixanol

OptiPrep is a ready-made, sterile and endotoxin-tested solution of iodixanol that works cross research and clinical workflows, giving you control over your virus purification. Iodixanol can also be used to separate full and empty viral particles, as well as to isolate different cell types and organelles.
