Sera (Serum)

Sera, whether bovine, human or from other sources, provides mammalian cells with the vital growth factors, lipids and more required for their growth in culture. The type of sera required is determined by both the cells being used and the media those cells require. Serum is a traditional supplement used in cell culture. Serum provides critical nutrients and growth factors needed by the cells for optimal growth. Fetal Bovine Serum (FBS) is the most common serum used for this purpose; however, there are other serum types used in the culture of cells. Serum alternatives are also available to support cell growth if applicable for the cell type. Avantor offers a wide variety of sera to meet the needs of cell culturists. Please select from the attributes below to find the sera options best suited to your application needs.
