Patent number: 10624962Abstract: A detoxified recombinant E. coli heat-labile enterotoxin mutant, LTS61K, is employed as a carrier protein to conjugate polysaccharide. The LTS61K contains a mutated mature sub-unit A (LTA) that includes lysine at amino acid position 61 and a wild-type mature sub-unit B (LTB). Various types of bacterial capsular polysaccharide antigens were chemically conjugated with the LTS61K protein by a reductive amination reaction. The conjugated polysaccharide-LTS61K products were physically, chemically and biochemically identified as soluble form. Rabbits were immunized intramuscularly to determine the immunogenicity of conjugated vaccines by ELISA to detect anti-polysaccharide antigen IgG titers and serum bactericidal assay thereby determining the functional activity of the antibodies. Study results show that conjugated polysaccharide-LTS61K vaccines induce higher polysaccharide-specific IgG titers and greater bactericidal activity in sera than that of polysaccharide alone or polysaccharide mixed with LTS61K.Type: GrantFiled: April 29, 2011Date of Patent: April 21, 2020Assignee: DEVELOPMENT CENTER FOR BIOTECHNOLOGYInventors: Yu-Shen Hsu, I-Ling Kou, Kuo-Chan Hung, Yuan-Hsin Lu, Ta-Tung Yuan

Patent number: 8961971Abstract: This invention relates to bispecific antibodies having combinations of linker and hinge sequences to create linker-hinge interface domains with biological significance. Such linker-hinge interface domains covalently join two molecules, maintain the biological activities of linked molecules (target binding), stabilize the biological characteristics of new molecule (solubility and 4° C. stability), maintain the chemical, biochemical and physical properties (cytotoxicity) of the linked molecules, and modulate the biological characteristics of the linked molecules (activating T-lymphocytes without significant sign of proliferations). Both linker (GGGGS) and hinge (CPPCP) sequences are required to establish functional linker-hinge interface domains as deletion of any of the component resulted in significant lost of T-lymphocyte mediated activity.Type: GrantFiled: December 19, 2012Date of Patent: February 24, 2015Assignees: Development Center for Biotechnology, DCB-USA LLCInventors: Yu-Shen Hsu, Show-Shan Sheu, Ming-I Chang, Ming-Chuan Chang, Ta-Tung Yuan
