Product Introduction

Tobitec FA &FB are chemically-defined feeding mediums without animal-derived components, growth factors, polypeptides, hydrolysates and phenol red, containing amino acids, vitamins, glucose, inorganic salts, and trace elements. Our products are highly efficient feeding mediums specially designed for improving CHO cell growth and production, which can satisfy the nutrient needs from high cell density culture and high level expression. Our products are also suitable for different cell lines including CHO-K1, CHO-S, DG44, CHO-ZN, etc, selected by GS system and DFHR system. Using appropriate feeding strategy based on cell strain traits can significantly improve cell growth and expression level and quality of antibody.
