Serum-free and serum-reduced cell culture: cultivated meat, vaccines, and recombinant proteins
Plant- and yeast-derived cell-grade hydrolysates in place of part of the serum
THE SITUATION AND THE PAIN POINTS
Fetal bovine serum is costly, variable, and carries animal-origin risk; cultivated meat and biologics are both seeking alternatives. Most peptones, however, carry too much endotoxin and impurity for cell culture.
OUR APPROACH
STBIO's cell-grade hydrolysates are microfiltered or ultrafiltered to keep endotoxin and impurities within cell-culture limits, supplying amino acids, peptides, and growth factors under serum-free or low-serum conditions for mammalian, insect, and cultivated-meat cell lines.

Frequently asked questions
01Can hydrolysates fully replace serum?
It depends on the cell line. Hydrolysates typically cut serum by half or more; fully serum-free culture usually also needs other growth factors and formulation work. Trial samples and literature are available.
