**Fetal Bovine Serum: Uses, Benefits, and Best Practices in Cell Culture**
Fetal Bovine Serum (FBS) is one of the most widely used supplements in biological research and cell culture. Derived from the blood of bovine fetuses, it is a rich source of essential nutrients, growth factors, and hormones that support the growth and maintenance of cells in vitro. Because of its unique composition and reliability, FBS remains a cornerstone in laboratories working in biotechnology, pharmaceuticals, and academic research.
One of the primary reasons for the popularity of Fetal Bovine Serum is its ability to promote cell proliferation. It contains a balanced mixture of proteins, vitamins, trace elements, and lipids that are crucial for cell survival. Additionally, it provides growth factors that stimulate cell division and attachment, making it especially valuable for culturing a wide range of cell types, including primary cells and established cell lines.
