Latest Patents

Weiqiang Gao holds a patent for a fluorogenic substrate designed for measuring ADAMTS13 activity or ADAMTS13 inhibitor activity. This innovative substrate comprises an oligopeptide that can consist of up to 80 amino acids from the sequence of von Willebrand Factor (VWF). The oligopeptide includes modifications such as an amino-terminal glycine, a scissile Y-M peptide, and a cysteine substitution located from 1 to 12 amino acids from the scissile Y-M in the carboxy terminal direction. Additionally, the substrate features a fluorophore and a fluorescence quencher bound to the oligopeptide on opposite sides of the scissile Y-M peptide, ensuring that the fluorescence quencher is not identical to the fluorophore. The oligopeptide can also be encoded by a nucleic acid sequence that may include a His tag and can be expressed in a cell or microorganism. Methods for using this fluorogenic substrate to measure ADAMTS13 activity or ADAMTS13 inhibitor activity are also disclosed in the patent.
