Charcoal/Dextran Treated FBS is available for users requiring reduced levels of various hormones. High quality FBS is processed using a proprietary charcoal/ dextran treatment that has been shown to reduce the levels of many hormones and growth factors. This serum is assayed for a variety of components before and after treatment, thus assuring the efficacy of the treatment. Charcoal/Dextran FBS has been shown to be effective in reducing steroid levels for utilization in receptor studies or estrogen related investigations. Other studies indicate that charcoal/dextran treatments may be used to minimize lot-to-lot serum variability. Charcoal/Dextran FBS is filtered through three sequential 100nm (0.1 µm) pore-size rated filters.
