At Biotrend, we are committed to advancing your research and production processes by offering a complete range of high-performance media and tools. Our specialized solutions for insect, mammalian, and hybridoma cell cultures ensure optimal growth, scalability, regulatory compliance, and exceptional reproducibility — from small-scale studies to industrial manufacturing.
Explore our key offerings designed to enhance your cell culture and protein expression workflows:
Insect Cell Culture Media
Our ESF 921™ and ESF AF™ media are protein-free and animal-free, supporting high-density growth of Sf9, Sf21, Tni (High Five™), and S2 cells. Optimized for baculovirus expression systems (BEVS), they provide exceptional virus and protein yields. The Production Boost Additive (PBA) further enhances expression levels by maintaining cell viability during late-stage culture.
CHO Cell Culture Media
The CHO|ONE Media System™ and CHOventure™ offer chemically defined, scalable solutions for CHO-S, CHO-DG44, and CHO-K1 cells. Optimized for fed-batch processes, they deliver high protein titers while minimizing lactate and ammonia buildup. From research to industrial production, these media guarantee reproducible results across all scales.
Vero Cell Culture Medium
Our VeroVax and VeroPrime are serum-free, animal-origin free, and chemically defined media, optimized for the cultivation of Vero cells in vaccine and virus production. Designed for both adherent and microcarrier suspension systems, they ensure high viral titers and consistent growth. These media fully comply with biopharmaceutical regulations, supporting scalable, cost-effective manufacturing for clinical and industrial applications.
HEK Cell Culture Medium
The HEK|ONE System has been formulated to meet the exacting standards of therapeutic protein and viral vector production using HEK293 cells. Our HEK|ONE S medium optimizes stable expression processes, while HEK|ONE T medium is specifically tailored for efficient transient transfection, including compatibility with PEI-based protocols. Combined with the HEK|ONE Feed supplement, these solutions provide unparalleled viability, growth rates, and transfection efficiencies, supporting both early research and large-scale manufacturing objectives.
Hybridoma Expression Media
HybridomaPlus offers a ready-to-use, animal-free, serum-free, and protein-free medium for antibody production, supporting both suspension and adherent hybridoma cultures. The Hybridoma Supplement enhances cloning efficiency without requiring feeder layers, simplifying the path to high-yield monoclonal antibody generation.
Flasks and Accessories
We offer Ultra Yield flasks designed for high-density bacterial cultures like E. coli, as well as aseptic Optimum Growth® sample flasks with one-way valves for safe sampling. Our disposable Erlenmeyer flasks provide cost-effective solutions for a variety of suspension cell culture applications across bacteria, fungi, animal, and plant cells.
