We have produced and characterized two chimeric human IgG1 monoclonal antibodies that bind different immunodominant epitopes on Vibrio cholerae lipopolysaccharide (LPS). MAb 2D6 IgG1 recognizes Ogawa O-polysaccharide antigen, while mAb ZAC-3 IgG1 recognizes core/lipid A moiety of Ogawa and Inaba LPS. Both antibodies were expressed using a Nicotiana benthamiana-based rapid antibody-manufacturing platform (RAMP) and evaluated in vitro for activities associated with immunity to V. cholerae, including vibriocidal activity, bacterial agglutination and motility arrest.
我们制备并鉴定了两种嵌合人IgG1单克隆抗体,它们可结合霍乱弧菌脂多糖(LPS)上不同的免疫显性表位。单克隆抗体2D6 IgG1识别小川型O-多糖抗原,而单克隆抗体ZAC-3 IgG1识别小川型和稻叶型LPS的核心/脂质A部分。两种抗体均使用基于本氏烟草的快速抗体制备平台(RAMP)表达,并在体外评估了与霍乱弧菌免疫相关的活性,包括杀弧菌活性、细菌凝集和运动抑制。
