Optimization & Transformation of Enzyme Molecules (IVD Use)

Watson has rich experience in enzyme resource exploration, optimization and transformation. It can explore new enzyme sources from huge enzyme resources and optimize and transform the most suitable enzyme molecules. Through the establishment of extensive and in-depth cooperation with the professional enzyme engineering research teams of many famous universities, Watson can grasp the frontier of enzyme engineering in time and quickly transform into the advanced technology of the company.

Watson can perform important enzyme functions such as enzyme activity, stability, substrate specificity, optimum pH, and organic solvent resistance. By rational design, new enzyme resources with greatly improved performance are quickly obtained to meet the application requirements of the target enzyme in different fields such as diagnosis, medicine, energy, washing and papermaking.

Optimizing Service of Freeze-drying Conditions of Protein (For IVD Use)

Proteins usually exist in solution after purification, but the storage time of protein solution is very short. A good freeze-drying process can preserve the activity of most proteins, improve the stability of proteins, prolong the storage time, and reduce the freight.

However, protein freeze-drying may cause loss of protein activity, aggregation and other denaturation problems. Watson has been exploring protein freeze-drying process for many years and has accumulated rich freeze-drying experience. It can customize protein freeze-drying process or optimize its original process for customers.
