Tet System Approved FBS

Description

Fetal Bovine Serum FBS that has been functionally tested for optimal use with all of our Tet Systems. This FBS does not contain trace levels of tetracycline or its derivatives which have been observed to interfere with proper regulation of TRE-controlled gene expression. Use of this serum ensures the maximal range of induction possible with the Tet Systems. Back Fetal bovine serum FBS approved for use with tetracycline inducible expression systems.Only Takara Bio USA functionally tests FBS to be sure that no contaminating tetracycline derivatives interfere with induced expression levels. Back Fetal bovine serum from Clontech is functionally tested to guarantee consistent results with tetracycline-inducible expression systems.Serum from other vendors that have not been functionally tested may contain tetracyclines that affect the maximum expression in Tet-Off systems, or generate background in Tet-On systems. Data here shows induction of luciferase expression from our CHO-AA8-Luc Tet-Off Control Cell Line using different sources of FBS. Back
