Title: Changlong Hao: Innovator in Food Safety Immunodetection
Introduction
Changlong Hao is a prominent inventor based in Jiangsu, China. He has made significant contributions to the field of food safety through his innovative research and development of monoclonal antibodies. With a total of 2 patents, his work focuses on enhancing the detection of harmful substances in food products.
Latest Patents
Changlong Hao's latest patents include the development of an anti-phenacetin monoclonal antibody hybridoma cell strain AD and its preparation method and application. This invention relates to the technical field of food safety immunodetection. The monoclonal antibody hybridoma cell strain, named monoclonal cell strain AD with the number CGMCC19681, is designed to detect phenacetin residues in food. The method involves the use of a hapten coupled with a carrier protein to prepare an immunogen, which is then used to immunize mice and create hybridoma cell lines. The resulting monoclonal antibody has shown good affinity and detection sensitivity for phenacetin, making it a valuable tool for food safety.
Another significant patent is the anti-dinitolmide monoclonal antibodies and the hybridoma cell strain that secretes them. This hybridoma cell strain, DAS3H10, is applicable to food safety immunoassay methods. It has been deposited in the Comprehensive Microbiology Center of China Microbial Culture Collection Management Committee, with a deposit date of November 28, 2019. The monoclonal antibody secreted by this strain exhibits high sensitivity to dinitolmide, allowing for the preparation of immunoassay kits and colloidal gold test strips for detecting dinitolmide in animal-derived foods.
