Our research services include microbial strain engineering, high-producing strain screening, and protein or plasmid preparation. We have been involved in the research, development and manufacturing of various large molecules, including recombinant subunit vaccines, virus-like particles (VLPs), Nano-antibodies/ heavy-chain variable (VHH)/ single domain antibody (sdAb), antibody fragments (Fab, scFv), peptides/hormones (insulin, GLP-1, growth hormone), cytokines (Interleukin-2/IL-2, IL-15, IL-21), growth factors (EGF, FGF, NGF, KGF, KDGF), enzymes, plasmid DNA, collagens, etc.
