Publication number: 20240141061Abstract: The present disclosure relates to an antibody binding specifically to CD55 or an antigen-binding fragment thereof; and a composition for preventing, treating and/or diagnosing cancer containing the same. The antibody of the present disclosure may be used as an effective therapeutic composition for various CD55-mediated diseases since it shows high binding ability and inhibitory effect for the CD55 protein which promotes tumor growth by inhibiting the complement immune mechanism. In addition, the antibody of the present disclosure may be usefully used as an effective therapeutic adjuvant that fundamentally removes drug resistance and remarkably improves therapeutic responsiveness in various diseases in which resistance to therapeutic agents with CDC (complement-dependent cytotoxicity) as a mechanism of action has been induced due to overexpression of CD55.Type: ApplicationFiled: January 12, 2022Publication date: May 2, 2024Applicants: SG MEDICAL INC, KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATION, KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Ji Chul LEE, Hye In PARK, Sung-Won MIN, Sung-Won MIN, Hyeong Sun KWON, Jae Cheong LIM, So Hee DOH, Eun Ha CHO, So-Young LEE, Sung Hee JUNG

Patent number: 8367885Abstract: This invention relates to a method of preparing a multicomponent bismuth molybdate catalyst by changing the pH of a coprecipitation solution upon coprecipitation and a method of preparing 1,3-butadiene using the catalyst. The multicomponent bismuth molybdate catalyst, coprecipitated using a solution having an adjusted pH, the preparation method thereof, and the method of preparing 1,3-butadiene through oxidative dehydrogenation using a C4 mixture including n-butene and n-butane as a reactant are provided. The C4 raffinate, containing many impurities, is directly used as a reactant without an additional process for separating n-butane or extracting n-butene, thus obtaining 1,3-butadiene at high yield. The activity of the multicomponent bismuth molybdate catalyst can be simply increased through precise pH adjustment upon coprecipitation, which is not disclosed in the conventional techniques.Type: GrantFiled: May 8, 2008Date of Patent: February 5, 2013Assignees: SK Innovation Co., Ltd, SK Global Chemical Co., Ltd.Inventors: Young Min Chung, Seong Jun Lee, Tae Jin Kim, Seung Hoon Oh, Yong Seung Kim, In Kyu Song, Hee Soo Kim, Ji Chul Jung, Ho Won Lee
