This means that there can be big differences between FBS-batches with different amounts of endotoxins and other undesired elements as well as other unwanted, and unknown, substances which affect the growth of cell cultures in different ways. The use of foetal calf serum therefore makes scientific research less reliable, harder to reproduce and experimental results harder to compare. It is therefore much harder to make use of the research. Read more…

It is estimated that in Europe production takes place in about 25 slaughterhouses, but it is thought that there is considerable hidden production – one reason being that slaughterhouses do not provide information on this niche-production.
