Recombinant Protein Expression Service

Recombinant protein is a protein encoded by a recombinant DNA that has been cloned in a system that supports the expression of the gene and translation of mRNA. The host cells used for recombinant protein production can be derived from bacteria, mammalian cells, insects and yeast. Recombinant proteins have been widely used in most hot research areas such as immune checkpoints, antibody-drug targets, CAR-T cell therapy targets, Fc receptors, influenza viral proteins and cytokines.
