The problem: Trace tetracycline contaminants in standard Fetal Bovine Serum (FBS) can alter experimental results by enabling background expression in Tet-On Systems and suppressing maximum expression levels in Tet-Off systems.

The solution: Functional testing makes our FBS superior because it ensures that you will be able to achieve the full range of inducibility and the lowest background possible with our Tet Systems.
