Structural Biology

We have significant experience in the expression and purification of recombinant proteins. We utilise various protein expression modalities, including prokaryotic protein expression, yeast protein expression, insect cell protein expression (baculovirus), and mammalian cell protein expression systems. In addition, we have employed fusion technologies to provide our clients with more options in terms of protein expression and purification. We tailor our service for your project including the design, gene optimization, expression condition optimization, and purification technology system to deliver your target protein quality and expression level.

The measurement of complete three-dimensional structure of protein and its complex assembly is the scientific basis for studying the relationship between molecular structure and function in life activities and revealing the physical and chemical nature of life phenomena. The X-ray diffraction of protein and its complex crystals is one of the main methods to study the three-dimensional fine structure of biological macromolecules.

We provide complete sets of M9 selenomethionine (SeMET) medium for IPTG-induced E.coli expression system, production of selenomethionine-labeled protein and protein crystallography using multi-wavelength anomalous diffraction (MAD).
