Definition

culture medium that contains no serum

Semi-Formal Definition:

every instance of ‘serum free culture medium’ is defined as exactly an instance of ‘culture medium’ that does not ‘has continuant part at some time’ some ‘serum’

Explanatory Notes

Serum-free media are media formulated without serum, reducing the variability and risks associated with serum-containing formulations. They provide essential nutrients and may include recombinant proteins (e.g., insulin, transferrin), chemically defined lipids, trace elements, or other additives to support robust cell culture. Serum-free media improve reproducibility, simplify downstream purification, and are widely used in biomanufacturing because they reduce regulatory concerns and enhance lot-to-lot consistency. Many serum-free formulations are also chemically defined, but some still include hydrolysates or other complex additives.

Examples

• CD-CHO (chemically defined CHO medium) contains recombinant insulin and transferrin, no serum

Counter-Examples

• CHO production medium supplemented with bovine serum albumin (BSA from serum)
