Over more than 11 years, CUSABIO has established five systems from prokaryotic to eukaryotic to express the recombinant protein. We own protein expression technology based on a series of protein expression and purification technology, including protein expression technology shown by Baculovirus outer membrane proteins (OMP), and membrane protein expression technology, etc.

The recombinant proteins we provide include cytokines (Interleukin, Interferon, Growth Factor, Tumor Necrosis Factor, Chemokine and Colony Stimulating Factor), Drug Target Protein (CD Antigen, FC Receptor, Immune Checkpoints), hormones, enzymes, viral antigens, allergens, human disease-related proteins, and animal and plant and microbial proteins, etc., of which there are 578 kinds of active proteins.
