Frequently Asked Questions
Is your fetal bovine serum BSE-free?
Yes. For more information: https://www.genengnews.com/insights/high-quality-fbs-may-come-from-any-authorized-country-of-origin/
What is fetal bovine serum?
Fetal bovine serum is derived from the blood of fetal calves and contains the nutritional and macromolecular growth factors that are essential for the growth and maintenance of cultured cells.
What is the difference between fetal bovine serum and fetal calf serum?
Fetal bovine serum (FBS) and fetal calf serum (FCS) are used to describe the same product and are interchangeable, although the use of FBS is more common. Bovine calf serum (BCS) has notably different characteristics than fetal bovine serum and is derived from calves post-birth,.
How should serum be thawed?
We recommend thawing serum overnight at 2-8°C.
How long can thawed serum be stored?
Serum should be used within 2-4 weeks when stored at 2-8°C.
How long can I store thawed serum at 2-8°C?
Serum should be used within 2-4 weeks when stored at 2-8°C.
Can I aliquot and refreeze serum?
Yes. Many researchers will aliquot serum into smaller volumes and refreeze until needed.
If my FBS arrives partially thawed, can I still use it?
We take every precaution to ensure FBS arrives frozen. If your FBS arrives partially thawed and is at least two-thirds frozen, it can be refrozen and used with confidence.
There are precipitates in the FBS, is this bad?
In almost every instance, the serum is not contaminated. It is usually the result of normal serum components. Fibrin (a non-globular protein involved in the clotting of blood) is most common. Fibrin appears in small quantities as a fine flake or may occur as a lump of a semi-solid substance.
Why would I use heat-inactivated serum?
Applications where heat-inactivated serum is recommended include immunological studies and culturing of embryonic stem cells (ESCs), insect cells, and smooth muscle cells.
How can I sample FBS or set up a reserve?
Your Genesee sales representative will be happy to assist you in getting a reserve set up for a specific lot or testing to see what lot may work best for you.
