Description
Charcoal-Stripped Fetal Bovine Serum (CS-FBS)
Background
Charcoal-Stripped Fetal Bovine Serum (CS-FBS) is the outcome of treating the Fetal Bovine Serum or Calf serum with activated carbon removes hormones and steroids from FBS.
- This process removes all the non-polar material such as lipophilic (lipid-related) materials (viruses, certain growth factors, hormones, and cytokines).
- Acts as an effective blocker agent in immunoassay systems as well as immunoprecipitating analysis (by coating the Sepharose-activated beads in order to prevent nonspecific binding).
- Moreover, it performs the function regardless of the molecular weight of the target.
PurMa Biologics applying Norit A charcoal coated with Dextran T-70 which manufactures a high-quality Charcoal-Stripped Fetal Bovine Serum.
PurMa™ Charcoal-Stripped FBS (DFBS)
- PurMaTM Premium FBS is USA origin.
- Goes through Heat in activation and gamma irradiation.
- Following the stripping, the FBS goes through heat inactivation process.
- PurMa Biologics perform vigorous analysis following the stripping and will provide a certificate of analysis.
- The procedure depletes any residue of mycoplasma, steroids and hormones, and other pathogens.
- Acceptable level of endotoxin (10 mg/Dl) and hemoglobin (20 mg/Dl).
- Due to the loss of a vast variety of hormones and steroids (such as growth factors), we recommend using 15-20% CS-FBS in your media to make sure cultured cells are well beings.
