Download this note (PDF) Traditional mammalian cell culture is usually anchor-dependent and serum-supplemented. Animal-derived components tend to introduce lot-to-lot variability and blood-borne pathogens. Use of serum also tends to increase immunogenicity and production costs. Because of these issues, suspension cultures in animal-derived component free (ADCF) cell culture media are usually preferred for situations like recombinant […]
