Very high quality Fetal Bovine Serum (FBS) is used in the manufacture of J R Scientific’s (JRS) Charcoal / Dextran Treated FBS (CDFBS). Using a proprietary method JRS processes FBS through a series of CD treatments to reduce the levels of many hormones, growth factors and steroid levels. This product is available for those scientists requiring lower levels of these components in their studies to include receptor or estrogen related investigation. We measure various hormones and steroids pre and post treatment to ensure our process provides consistent and repeatable results.
