Application

FBS sourced in the United States is used in a broad range of cell culture applications. FBS provides many non-defined growth promoting and survival enhancing factor to cells in culture. Charcoal stripped FBS is often used instead of FCS to minimize the level of androgen and other hormones provided in 10% serum supplemented media.

Biochem/physiol Actions

Charcoal Stripped Fetal Bovine Serum (FBS) is available for researchers requiring decreased levels of various hormones in their studies. Dextran treated Charcoal is used to selectively remove hormones without nonspecific loss of other serum components. The effectiveness of hormone removal is assessed on the basis of reductions in the levels of T3, T4, and Progesterone pre and post treatment.

This product is designed for researchers involved in studying processes influenced by steroid hormones such as estrogen stimulation and the obesity process and other areas that benefit from reduced hormone levels such as certain types of viral infections.

  5. Once a bottle of Fetal Bovine Serum (FBS) is thawed, for how long can the bottle be used?

    Once Fetal Bovine Serum has been thawed, the bottle can be used in cell culture for up to 7 days for most cell types when stored  refrigerated at 2-8°C.  If the cells are not fastidous (e.g. HeLa or fibroblasts), the thawed and refrigerated serum can be used for up to 30 days.  For some extremely fastidious cell lines, it may be necessary to screen individual lots for acceptable performance.  For uses such as blocking for various immuno procedures, usage will generally be for 30 days and perhaps somewhat longer when stored at 2-8°C.  For other procedures, usage beyond 30 days storage at 2-8°C will need to be determined.
