Latest Patents
One of Cheng Li's latest patents is the "Pro-insulin aspart structure and method for preparing insulin aspart." This invention provides a novel pro-insulin aspart structure design and a method for its preparation. The method involves designing the pro-insulin aspart sequence, constructing recombinant insulin aspart engineered bacteria, and inducing the expression of an insulin fusion protein as an inclusion body in the engineered bacteria. The extraction process of the insulin fusion protein includes denaturing, renaturing enzymatic digestion, and separation purification operations. By modifying the recombinant leading peptide and C-peptide sequences, this method eliminates the need for a cyanogen bromide cleavage step, enhancing the overall efficiency of the process. Additionally, the C-peptide can be replaced by a single amino acid, which helps reduce quality loss associated with enzymatic digestion.
Another significant patent is the "Trace chain information query method and device." This application outlines a method for querying trace chain information, which includes receiving first and second trace chain information from different service nodes triggered by the same user operation. The trace chain server identifies and finds the relevant information based on a group identifier, facilitating efficient data management and retrieval.
