Product identifiers
US Origin fetal bovine serum charcoal/dextran stripped to remove steroid hormones, growth factors, and lipophilic compounds. The charcoal stripping process significantly reduces estradiol, progesterone, testosterone, cortisol, and thyroid hormones — creating a hormone-depleted serum essential for steroid receptor research and hormone-sensitive cell culture.

Decide once
Five buyer paths and the honest verdict for each. Pick this grade only if your job-to-be-done is in the list.
Yes, this grade. Charcoal-stripped FBS reduces endocrine-active background while preserving cell-culture viability. Use it when serum hormones would confound dose response, receptor activation, or pathway readouts.
Yes, this grade. Use for low-background receptor-binding studies, steroid receptor ChIP-seq, and ER-positive or AR-positive cancer models where residual hormone signal must be controlled lot by lot.
Use only if documentation requires it. Standard FBS is usually the better value for routine growth. Charcoal-stripped FBS carries a cost premium and may alter growth behavior without improving non-endocrine workflows.
Request a sample first. Hormone and lipid-soluble compound depletion can change attachment, proliferation, or differentiation behavior. Pilot the exact lot before scale-up, especially for sensitive primary or stem-cell systems.
Confirm the protocol requirement. Choose charcoal-stripped only when the method requires hormone-depleted serum. If the gating issue is geographic origin or regulatory traceability, route the requirement through documentation review first.
