Fetal Bovine Serum (FBS) 500 mL: A Gold-Standard Supplement for Advanced Cell Culture Research 

Fetal Bovine Serum (FBS) 500 mL remains one of the most essential and widely used supplements in research laboratories across the world. As a rich source of growth factors, hormones, and essential nutrients, FBS provides the ideal environment for the survival, growth, and maintenance of cultured cells. Whether you are involved in molecular biology, stem cell research, vaccine development, or protein expression studies, high-quality FBS is a fundamental tool in ensuring experimental success.

Trusted as a premium Cell Culture Reagent, FBS is valued for its consistency, purity, and ability to promote cell health. It is one of the most versatile Lab Reagents available, widely used alongside Lab Chemicals and even compatible with certain Blot Reagents in protein analysis workflows. 

What Is Fetal Bovine Serum (FBS)?

Fetal Bovine Serum is derived from the blood of fetal calves and processed into a nutrient-rich serum used primarily for in vitro cell culture. Due to its high content of growth factors and low antibody levels, FBS supports a wide variety of cell types, including:

• Mammalian cell lines
• Primary cells
• Hybridomas
• Stem cells
• Recombinant protein-producing cells

Its naturally balanced composition makes it the preferred supplement in molecular biology, biochemistry, immunology, and pharmaceutical research.
