Microtest provides reliable testing of raw materials harvested from animal sources. Used for the production of biologic products, these materials are frequently produced from cows (e.g., fetal bovine serum) or pigs (e.g., trypsin).
However, this live-animal derivation carries the risk of virus contamination. Should source animals be infected with viruses at the time of harvest, any resulting lots of material could be contaminated.
Microtest complies with the virus testing for animal products described in the U.S. Code of Federal Regulations, Title 9 (9 CFR). The tests detect viruses in serum and trypsin, as well as in other culture media additives derived from animal sources.
We can also offer a modification of this testing. The cell lines used and the assay length remain the same, as indicated in the 9 CFR. The difference: this test modifies the endpoint so that more samples can be screened for viruses simultaneously — thus reducing costs.
