Fetal Bovine Serum (FBS) is the most frequently used growth supplement for cell culture media. FBS Tetracycline negative is suitable for applications with tet-inducible gene expression systems.
Description
Fetal Bovine Serum (FBS), Tetracycline Negative is widely used in eukaryotic cell culture, typically as a supplement for growth media. Fetal bovine serum contains nutritional and embryonic growth promoting factors that are essential for a successful cell culture. Further, fetal bovine serum contains various small molecules, such as, e.g., amino acids, lipids, sugars, and hormones.
Fetal bovine serum (FBS) is the blood component obtained after coagulation and removal of cellular components. Its unique and comprehensive mix makes FBS one of the most important supplements for supporting cell growth and proliferation for in vitro cell culture.
Our fetal bovine serum for cell culture supports most cell lines and undergoes strict quality controls.
Cell culture applications with tet-inducible gene expression systems and other applications, where the presence of tetracycline would be disturbing, require the use of a tetracycline-negative FBS. We have established a test with an external laboratory, using liquid chromatography-tandem mass spectroscopy to detect all kinds of tetracycline. This method allows accurate detection of Chlortetracycline and Oxytetracycline in a range of 0.05 mg/l.
胎牛血清中可能含有的微量抗生素四环素(tet),可以确保精确的基因表达。但是科研工作者在使用敏感四环素诱导调控表达系统时,往往会遇到意外的基因表达的问题。为确保精确的基因表达,血清中所含的四环素越少越好。本产品可应用于使用敏感四环素诱导表达系统的细胞培养,以及其它对四环素敏感的实验。四环素检测含量约为0.001 μg/mL。
