α-甘露聚糖肽 (Mannatide)是α-溶血性链球菌 (Alpha-hemolyticstreptococci)培养液中提取的具有多种生物活性的糖蛋白。自发现能够中和乙型肝炎病毒以来,大量的研究和药理试验证明,α-甘露聚糖肽具有抑制肿瘤、显著提高人体免疫功能的作用并应用于人医临床。目前,α-甘露 Mannatide is a glycoprotein with a variety of biological activity extracted from the culture of Alpha-hemolytic streptococci. Since the discovery of the ability to neutralize hepatitis B virus, a large number of studies and pharmacological tests have proved that α-mannan peptide has the function of inhibiting tumor and significantly improving human immune function and is applied to human clinical practice. Currently, alpha-nectar
