The hemolysin (HlyE) protein of Salmonella enterica serovar Typhi was reported to be antigenic. This work describes the cloning, expression, and purification of a hexahistidine-tagged HlyE protein under native conditions. Immunoblot analysis and a competitive enzyme-linked immunosorbent assay using sera from typhoid patients showed the presence of HlyE-specific antibodies in circulation.
肠毒素(HlyE)蛋白被报道具有抗原性。本工作描述了在天然条件下克隆、表达和纯化带有六组氨酸标签的 HlyE 蛋白。免疫印迹分析和使用伤寒患者血清进行的竞争性酶联免疫吸附试验显示循环中有 HlyE 特异性抗体的存在。
