Definition
culture medium that contains serum
Semi-Formal Definition:
every instance of ‘serum containing culture medium’ is defined as exactly an instance of ‘culture medium’ that ‘has continuant part at all times’ some ‘serum’
Explanatory Notes
Serum-containing media are historically the most common type of complete culture media, typically supplemented with fetal bovine serum (FBS), calf serum, horse serum, or other animal sera. Serum provides a complex, undefined mix of nutrients, hormones, adhesion factors, binding proteins, protease inhibitors, and detoxifying agents, making such media broadly supportive of many cell types. However, the presence of serum introduces lot-to-lot variability and potential contaminants, including adventitious agents, endotoxin, and mycoplasma. In biomanufacturing, serum use raises regulatory concerns, and the trend has shifted toward serum-free and chemically defined media to improve reproducibility and control.
Examples
- RPMI-1640 medium + 10% horse serum that is commonly used for hematopoietic cell lines
Counter-Examples
- Serum-free chemically defined medium; culture medium with hydrolysates (yeastolate, soy peptone, etc.) but no animal serum
