Preparation and immunogenicity of conjugates composed of the O-specific polysaccharide of Shigella dysenteriae type 1 bound to tetanus toxoid

LPS由类脂A、核心多糖和O-特异性多糖三部分组成。

The LPS molecule can be divided into three parts : lipid A , core polysaccharides and O-antigen repeats .

脂多糖（LPS）是内毒素的主要成分，来源于革兰氏阴性菌细胞壁的外膜，由核心寡聚糖、特异性多糖与类脂A组成，其中类脂A是LPS的活性部位以及毒力中心。

The main component of the endotoxin , lipopolysaccharide ( LPS ) derived from the outer membrane of Gram-negative bacteria cell wall is composed by the core oligosaccharide , specific polysaccharide and lipid A which is the active site and the center virulence of LPS .
