Gibco Tet-System Approved FBS has been functionally tested to offer researchers optimal control over their gene expression systems, thus minimizing challenges that can be posed by this type of reagent.
Functional, cell-based assays that detect the presence of tetracycline and its derivatives are used to select FBS that delivers the highest range of induction.
Why cell-based testing?
Speeds up your workflow
Enables more control in
"This product provide optimal control over my virus production"
—Biotech Researcher, Canada
"This product provides me confidence, convenience, and control over my research"
—Academic Researcher, USA
"I have greater control over my inducible expression systems"
—Biotech Researcher, United Kingdom
"I require tight control of gene expression and I need to ensure genes are not expressed until tetracycline is added in, so tet-free is a requirement."
—Biotech Researcher, USA
Case study results with Tet-System Approved FBS
A biomanufacturing organization looking to improve the safety of cell culture virus production has engineered a cell line that will only permit virus expression in the presence of tetracycline. Replacing traditional FBS with Tet-System Approved FBS improves control over when the virus is produced.
|Tet-System Approved FBS||-Tet|
|Tet-System Approved FBS||+Tet|
|Standard FBS with residual tetracycline||-Tet|
|Standard FBS with residual tetracycline||+Tet|
Use of Tet-System Approved FBS provides optimal control of the virus production.

Did you know?
Unintended expression can occur in very sensitive tet-inducible gene expression systems while using FBS. This happens because some lots of FBS contain residual amounts of the antibiotic tetracycline (tet) derived from animal treatment. It is important to use functionally tested FBS and don’t base your decisions solely on names like Tet-Free or Tet-Zero.
Using Tet-System Approved FBS is the most secure and shortest way for inducible expression systems
