應用
金黄色葡萄球菌来源肽聚糖用于：
- 刺激淋巴细胞：肽聚糖激活Toll样受体2 (TLR2)，存在于哺乳动物细胞中。它作为聚肌胞的拮抗剂
- 用于通过腹腔接种至单独样本刺激g型溶菌酶
- 用在磷酸盐缓冲液中并注射到露斯塔野鲮鱼中，进而研究其对核苷酸结合的寡聚化结构域-2 (NOD-2)基因表达的影响
生化／生理作用
革兰氏阳性细菌的细胞壁主要由肽聚糖组成。它由肽桥互相连接的多糖链组成。这种肽聚糖使细胞壁具有一定的刚性，并使细胞具有机械强度。它是一种表面分子，能够刺激免疫反应，包括导致发热的细胞因子。
包裝
无底玻璃瓶。内容物在插入式融锥内。
其他說明
革兰氏阳性菌细胞壁的主要成分。由N-乙酰-D-葡糖胺和胞壁酸残基以β 1-4糖苷键交替相连形成的聚糖骨架组成。细菌肽聚糖的免疫活性；细菌细胞壁的肽聚糖类型及其分类学意义；在葡萄球菌感染期间对肽聚糖的抗体反应。
