Fetal Bovine Serum has been used to block the human induced pluripotent stem cells (hiPSCs) derived hepatocyte-like cells (HLCs) cells in phosphate buffered saline during immunofluorescence staining.
FBS sourced from USDA approved non-USA countries 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.

Biochem/physiol Actions

Fetal Bovine Serum (FBS) is used as a supplement to cell culture media. It provides many non-defined growth promoting and survival enhancing factors to cells in culture.


USDA Approved Sourcing refers to FBS produced from blood collected in countries outside of the United States that have been approved by the USDA (United States Department of Agriculture) for export of beef products into the United States. Eligible countries for export into the U.S. include Australia, Canada, Chile, Costa Rica, Honduras, Iceland, Japan, Mexico, New Zealand, Nicaragua, Uruguay. Foreign serum is tested to ensure the absence of exotic viruses before release by the USDA.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  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.

Allele-specific gene silencing by RNA interference (RNAi) is therapeutically useful for specifically inhibiting the expression of disease-associated alleles without suppressing the expression of corresponding wild-type alleles. To realize such allele-specific RNAi (ASP-RNAi), the design and assessment of small interfering RNA...
