An antigenic material having a molecular weight of 3800-4500, and useful in the preparation of an anticaries vaccine is produced from a known antigenic material, antigen I/II of molecular weight 185,000 daltons obtained from the culture supernatant of Streptococcus mutans. The smaller molecular weight fraction of the invention contains the same antigenic determinants as the known 185,000 dalton material but the lower molecular weight material can be used with less side effects. The antigenic material can be used for the production of vaccine preparations that could be administered parentally or by topical application to the gums.
一种分子量为 3800-4500 的抗原材料可用于制备抗龋齿疫苗,它是由已知的抗原材料,即从变异链球菌培养上清液中获得的分子量为 185,000 道尔顿的抗原 I/II 制成的。本发明中分子量较小的部分含有与已知的 185,000 道尔顿材料相同的抗原决定簇,但使用分子量较低的材料可减少副作用。这种抗原材料可用于生产疫苗制剂,这种疫苗制剂可用于亲体给药或局部涂抹牙龈。
