FBS, USDA Origin, Lipid-Depleted
Fetal Bovine Serum (FBS) is the most commonly used serum for cell-based applications which are an integral part of cell culture, vaccine development, and drug discovery as it provides the most nutrients for the widest range of cell types. FBS provides critical growth factors for optimal performance of cell cultures and cell growth.
Lipid Depleted FBS reduces the concentration of lipids (free fatty acids). Ideally for research applications where the normal concentration of lipids may interfere.
- USDA sourced serum
- Reduced concentration of lipids
Captivate Bio has teamed up with Biowest, a leader in the collection of animal sera, to distribute FBS to the scientific community.

What is the difference between US origin and USDA origin FBS?
USDA origin FBS is collected in countries which have been approved by the USDA for bovine serum importation into the United States. US origin FBS comes from USDA licensed abattoirs located entirely within the continental U.S. Certificates of Analysis are available with all FBS purchases. Supplementary Certificates of Origin are also available upon request.
Do you provide other FBS products in addition to US and USDA origins?
Yes, we have teamed up with Biowest, a global leader in serum supply, to procure and offer FBS to the US scientific community. In addition to US and USDA origin, we offer a wide range of custom options including heat-inactivated, gamma-irradiated, and tetracycline FBS.
What is the shelf-life of FBS?
Most FBS products that are stored appropriately have a 5-year shelf-life. Please refer to the expiration date noted on the product label and the Certificate of Analysis provided at time of purchase for FBS batches you received.
Do you offer discounted or free samples of FBS for lot validation?
Yes, please contact our customer service team for details where we will work with you on your specifications. Please note we will only hold lots for 14 days.
