Charcoal stripped FBS is used by researchers requiring low levels of hormones in the serum which may interfere with the experimental work. During the stripping process the serum is filtered through charcoal to remove non-polar material such as estradiol, progesterone, cortisol, testosterone, T3, T4 and insulin. Furthermore some growth factors and cytokines are removed resulting in a suppressed cell differentiation. The concentration of salts within the serum is not affected. Charcoal stripping does not entirely eliminate the content of the steroid hormones but minimizes lot to lot serum variability.
