Gibco Serum Delivers
All products may not be available in all regions due to importation regulations
US Department of Agriculture (USDA) safety tested for the absence of bluetongue and akabane from countries that are USDA-approved for importation into the US
Gibco fetal bovine sera offer excellent value for basic cell culture, specialty research, and specific assays, earning the trust of researchers with consistent quality and award-winning support that help you meet your research needs and budget requirements.
Note: Heat inactivation is performed in a 56 degrees C water bath for 30 min with swirling every 10 min or so for heat distribution and to lower the degree of protein aggregation/flocculant precipitation. Note: If the time or temperature is exceeded, the serum may thicken to a gel. If this occurs, the serum is no longer usable. Unnecessary heat inactivation can take up time and potentially lead to wasted reagents if a mistake is made during the protocol1.

FBS is added to culture medium at a concentration of 2-10% to provide attachment factors, nutrients, and hormones for mammalian cells, as well as to be a buffer against disruptions like pH changes and endotoxins. FBS has significant amounts of embryonic growth promoting factors like hormones, carrier proteins, and macromolecular proteins. It also has low levels of antibodies and other growth-inhibiting components. For most basal medium, 10% FBS is used. Some applications require up to 20% supplementation, so researchers need to determine what is optimal for their specific application and cell line.

This product can be stored at 4 degrees C for up to 4 weeks. Once the medium has been supplemented with serum, we recommend using it within 2-4 weeks.

We recommend thawing the serum overnight at 4 degrees C or in a 37 degrees C water bath, removing as soon as it is thawed. Once thawed, aliquot into single-use sizes and freeze the aliquots. Each aliquot should ideally be thawed only one additional time as repeated freeze-thaw cycles are not recommended.
