Patent number: 11365214Abstract: The invention relates to a method for the treatment of body fluid proteins, by which proteins from body fluids such as blood or urine are extracted by adding a certain proportion of high molecular polymer solution under low temperature condition followed by denaturation and reduction by adding a certain concentration of surfactant and tris(2-carboxyethyl) phosphine (TCEP) under a high temperature condition. Subsequently, the iodoacetic acid brushes grafted on silica microspheres called as solid-phase alkylation reagents are added into protein solution, which can react rapidly with the protein sulfhydryl group. After centrifugation, the microspheres are obtained and repeatedly washed with methanol and buffer to remove interferences such as sugars, salts, surfactants, lipids to obtain high-purity proteins, and finally protease is added to digest proteins into peptides. After centrifugation, the peptide products are obtained, and directly analyzed by liquid chromatography-mass spectrometry (LC-MS) system.Type: GrantFiled: July 12, 2017Date of Patent: June 21, 2022Assignee: DALIAN INSTITUTE OF CHEMICAL PHYSICS, CHINESE ACADEMY OF SCIENCESInventors: Lihua Zhang, Huiming Yuan, Zhigang Sui, Kaiguang Yang, Yukui Zhang
