High-Quality Tetracycline-Free Fetal Bovine Serum

Biowest offers premium fetal bovine serum (FBS) specifically designed for research involving tetracycline-inducible gene expression systems. Our FBS is rigorously tested and quality-controlled to ensure optimal performance in these sensitive applications.

Key Benefits:

Tetracycline-free: Eliminates interference with tetracycline-regulated gene expression systems.
Proven performance: Supports a wide range of cell lines and experimental conditions.
Stringent quality control: Manufactured under ISO 9001:2008 and ISO 13485:2012 standards.
Traceability: Sourced from BSE, FMD, and BVD-free regions.

Trust Biowest for your critical cell culture needs.

We deliver Biowest solutions across South East Asia (Singapore, Thailand, Vietnam, Indonesia, Philippines, Myanmar) and Across China Only.
