Abstract

Six different mouse monoclonal antibodies (MAbs) and a specific rabbit polygonal antibody were raised against listeriolysin. Four of the MAbs also recognized seeligeriolysin, and five cross-reacted with ivanolysin. The hemolytic activity could be neutralized by the polygonal antibody as well as by five of the MAbs. None of the neutralizing antibodies interfered with the binding of listeriolysin to the cellular membrane. The epitopes recognized by the MAbs were localized by using overlapping synthetic peptides between positions 59 and 279, a region hitherto not implicated in mediating hemolytic activity.

摘要

针对李斯特菌溶血素制备了六种不同的小鼠单克隆抗体(MAb)和一种特异性兔多克隆抗体。其中四种单克隆抗体也识别海氏李斯特菌溶血素,五种与伊万诺夫溶血素发生交叉反应。多克隆抗体以及五种单克隆抗体均可中和溶血活性。所有中和抗体均不干扰李斯特菌溶血素与细胞膜的结合。利用59至279位之间的重叠合成肽确定了单克隆抗体识别的表位,该区域迄今未被认为与介导溶血活性有关。
