Protein expression technology is also called recombinant or fusion protein technology, which refers to a process to obtain target protein by ways of genetic engineering. There are two primary aspects of recombinant protein expression technology, namely, the expression of the target protein and the purification of the target protein. There are various expression systems for the expression of recombinant proteins, the basic technology of all of which are relatively mature. We possess a mature protein expression platform, including prokaryotic expression and yeast expression systems, and downstream recombinant protein purification technology. In terms of protein purification, we adopt mainstream chromatography technology in protein purification. We also provide a series of protein related services such as 2D electrophoresis and amino acid sequencing.

Antibodies are proteins produced by living organisms in response to exogenous substances, and can specifically identify the exogenous substances. Owing to their special properties, antibodies are widely used. Antibody preparation is the process in which specific antibodies are obtained by immunising animals with designed antigens.
We started to build antibody preparation platform in 2011 and we currently have production and testing platforms for polyclonal antibodies and monoclonal antibodies. As at 30 June 2017, we carried over 12,000 types of antibodies. Based on our current production platform, we have developed antibody services including production of antibodies and related immunology experiments.
