Gibco™ Exosome-Depleted FBS streamLines and standardizes cell culture workflows for exosome research. It is ready to use and performance tested to help save time and enable optimal exosome preparations.

  • Lowest exosome background
  • Enables consistent results: each lot tested for cell culture performance
  • No preparation needed: ultracentrifugation is not required

Exosome-Depleted FBS has been depleted of ≥90% of endogenous exosomes and is intended for use in cell culture exosome isolation assays. Every lot is tested for exosome depletion and culture performance, and our standard quality control assays are conducted to help ensure optimal and consistent results. This ready-to-use FBS for cell culture exosome isolations helps eliminate the risks associated with FBS reagent preparation by ultracentrifugation, for optimal assay results and increased experimental throughput.

For research use or further manufacturing use only. Serum and blood proteins are not for direct administration into humans or animals.

Frequently asked questions (FAQs)

What are the benefits and disadvantages of using heat-inactivated FBS in cell culture?

  1. Heating inactivates complement. Active complement can participate in cytolytic events, contract smooth muscle, release histamine from mast cells and platelets, and activate lymphocytic and macrophage cells. Applications where heat-inactivated serum is recommended include immunological studies and culturing of embryonic stem cells (ESCs), insect cells, and smooth muscle cells.
  2. Heat inactivation helps to achieve bottle-to-bottle and lot-to-lot stability by neutralizing many factors that can vary largely from lot to lot.
  3. There aren't necessarily disadvantages to heat inactivation of FBS, but there is some evidence that suggests there may be no added benefit to it unless you are carrying out immune studies.

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.

How long can I store Gibco Fetal Bovine Serum at 4 degrees C?

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.

How should I thaw Gibco Fetal Bovine Serum?

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.

How can I minimize lot-to-lot variability in serum?

You can test each new lot to be sure that it works for your specific applications. Alternatively, our serum sales team can determine the most consistent, highest-performing serum lot available using the Gibco iMatch Sera Lot Matching Tool.

Can I aliquot and refreeze serum?

Yes, after the overnight thaw, you can aliquot the serum into smaller, single-use aliquots and refreeze it.
