Multiple options are available for media free of human or animal-derived organic products, growth factors, hormones or other components. Instead, serum replacements, recombinant proteins and highly characterized components, defined chemically and by concentration, provide nutrients and promote cell functions such as proliferation and attachment.
Individual Growth Factors and Cytokines themselves are also provided in animal-component-free options, where available. These Animal-Free recombinant proteins are made using non-mammalian system components and processes, which researchers often select for stem cell cultures, serum-free applications, chemically-defined media and other in vitro pre-clinical work. These lab workers must reduce or eliminate altogether any risks of contaminating growth factors, viruses, prions and animal-derived ingredients. Our animal-free proteins are manufactured using an E.coli-based system, an animal-free facility, fermenter, columns, filters, labware, lyophilization and storage, and NO FBS or animal-derived ingredients. Quality standards include endotoxin levels <1.0 EU/ug protein, purity levels >/= 95% and bioactivity comparable to recombinant protein produced in traditional techniques.
