Latest Patents

Qinghong Shi's latest patents include a "Method for constructing a novel affinity peptide library for binding immunoglobulin G based on a protein affinity model of protein A." This innovative approach involves constructing an affinity peptide library of IgG using a simplified Protein A affinity model. The method utilizes the Molecular Mechanics—Poisson-Boltzmann surface area (MM/PBSA) technique to identify high-affinity hot spots of Protein A for human IgG. The resulting affinity peptide ligands are effective in purifying IgG through affinity chromatography.

Another notable patent is the "Method of protein refolding with ion exchange resins and the application of the same." This method outlines a systematic approach to refolding denatured proteins using ion exchange resins. The process includes selecting an appropriate resin, preparing it by removing heterogeneous ions, and mixing it with a refolding buffer to facilitate the refolding of proteins. The final step involves collecting the refolded protein solution through centrifugation or settlement.
