Yes, the concentration is different, generally between 5% and 10%, and the concentration is 20%. 
Third, the overall analysis
The fetal cow itself lives in a clean environment, and its serum is isolated from the outside world. As long as the production process is scientific and standardized, its quality is definitely better than the latter two. It is recommended that the general selection of serum types can be selected according to the ATCC and experimental needs.
