Methods for making an immunogenic conjugate that includes a hapten or an antigen covalently linked to a carrier. The methods include reacting a first agent with a dihydrazide resulting in a hydrazino-modified first agent, wherein the first agent is a hapten, an antigen or a carrier; reacting a second agent with a benzaldehyde compound resulting in a benzaldehyde-modified second agent, wherein the second agent is a hapten, an antigen or a carrier, provided that the first agent or the second agent is a carrier; and reacting the hydrazine-modified first agent with the benzaldehyde-modified second agent resulting in an immunogenic conjugate comprising a hapten or an antigen covalently linked to a carrier via a hydrazone linkage.
制造免疫原性共轭物的方法,该共轭物包括与载体共价连接的合体或抗原。这些方法包括:将第一制剂与二酰
肼反应,得到酰
肼修饰的第一制剂,其中第一制剂是单体、抗原或载体;将第二制剂与
苯甲醛化合物反应,得到
苯甲醛修饰的第二制剂,其中第二制剂是单体、抗原或载体,前提是第一制剂或第二制剂是载体;使
肼改性的第一制剂与
苯甲醛改性的第二制剂反应,产生免疫原性共轭物,该共轭物包括通过腙连接与载体共价连接的单体或抗原。
