Patent number: 12220464Abstract: The present invention relates to novel linkers containing a 2,3-disubstituted succinic group, or 2-monosubstituted, or 2,3-disubstituted fumaric or maleic (trans (E)- or cis (Z)-butenedioic), or acetylenedicarboxyl group for conjugation of a cytotoxic agent, and/or one or more different functional molecules per linker to a cell-binding molecule, through bridge linking pairs of thiols on the cell-binding molecule specifically. The invention also relates to methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.Type: GrantFiled: June 23, 2021Date of Patent: February 11, 2025Assignee: Hangzhou DAC Biotech Co., Ltd.Inventors: Robert Yongxin Zhao, Qingliang Yang, Yuanyuan Huang, Shun Gai, Linyao Zhao, Hangbo Ye, Huihui Guo, Qianqian Tong, Minjun Cao, Junxiang Jia, Chengyu Yang, Wenjun Li, Xiaomai Zhou, Hongsheng Xie, Chen Lin, Zhixiang Guo, Zhicang Ye

Patent number: 12216115Abstract: The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.Type: GrantFiled: April 29, 2022Date of Patent: February 4, 2025Assignees: CHENGDU SHEN MINDRAY MEDICAL ELECTRONICS TECHNOLOGY RESEARCH INSTITUTE CO., LTD., SHENZHEN MINDRAY BIO-MEDICAL ELECTRONICS CO., LTD.Inventors: Wenjun Tong, Yijie Yang, Huaming Xu, Xing Shi
