Large-Scale Fermentation Services

KMD Bioscience has been striking on recombinant protein expression and antibody development for many years, and we understand the need for purification, to produce clean, reproducible results. Large quantities of highly pure protein are a prerequisite for functional analysis and structural biology. With the rapid development of the protein drug market, the demand for large-scale protein production is increasing. We can offer industry-scale protein fermentation services, to meet high-throughput and large-scale production requirements.

KMD Bioscience possesses mature protein expression system and advanced protein expression technology. We have various fermentation tanks, bioreactors and protein purification systems, which can provide recombinant proteins from milligram level to gram level. According to customers' specific needs, we can also offer customized expression system and fermentation protocol.


High-Density Fermentation:


Our fermentation services include normal fermentation, high-density fermentation, and process optimization. High-density fermentation is an effective method to achieve high-yield recombinant protein. With our professional protein development platform, KMD Bioscience can provide customers with high-density fermentation technology services of different volumes. The capacity of our recombinant antibody production is as high as 4.7g/L.
