(一)人工合成佐剂-胞壁酰二肽(简称MDP),具有佐剂活性所需的最小结构,免疫佐剂活性较强而无副作用。在机体内可明显地增强体液抗体水平和促进细胞免疫的应答反应。在生理盐水中可行各种途径的免疫接种,甚至口服仍有效。MDP不仅无毒性,鲎试验证明不含内毒素,皮下注射亦不形成硬结,比常用的铝佐剂如氢氧化铝,磷 (A) synthetic adjuvant - muramyl dipeptide (MDP), with the minimum structure required for adjuvant activity, immune adjuvant activity without side effects. In the body can significantly enhance the level of humoral antibodies and promote cellular immune response response. Various routes of immunization are practicable in saline, even orally. MDP is not only non-toxic, 鲎 test proved no endotoxin, subcutaneous injection nor induration, than the commonly used aluminum adjuvants such as aluminum hydroxide, phosphorus
