Results Both GAMP-ADH and GAMP-ADH-Pep10 showed GAMP antigenic specificity. The serum IgG level against GAMP induced by GAMP-ADH-Pep10 conjugate was significantly higher than that by GAMP and showed no significant difference with that by GAMP-ADH-TT vaccine. The conjugate also induced immunological memory.

结果 所制备的多糖衍生物GAMP-ADH及多糖-蛋白结合物GAMP-ADH-Pep10均具有GAMP抗原特异活性，免疫小鼠后可诱生比多糖单独免疫更高水平的GAMP血清IgG抗体，且接近GAMP-ADH-TT疫苗诱生的抗体水平，并能形成免疫记忆。
