Product type
Fetal Bovine Serum (FBS) is a common supplement used in cell culture media to provide essential growth factors, hormones, and nutrients for the cultivation of mammalian cells. It is derived from the blood of fetal calves and is known for its rich composition, which supports cell growth and proliferation. FBS is widely utilized in various research and industrial applications, particularly in the fields of biotechnology and pharmaceuticals.
| Source | Derived from fetal bovine blood |
| Typical volume | 500 mL to 1 L |
| Storage temperature | Stored at -20°C or colder |
| pH range | 6.5 to 7.5 |
| Endotoxin level | Typically < 10 EU/mL |
