For researchers requiring high-quality cell culture media, Astor Scientific offers a tetracycline-free fetal bovine serum that is functionally tested for optimal use with all Tet Systems. This serum ensures the maximal range of induction possible with Tet Systems, as it does not contain trace levels of tetracycline or its derivatives, which have been observed to interfere with proper regulation of TRE-controlled gene expression. It is recommended to store this serum at -20°C to maintain its efficacy.
