佐剂可以增强免疫反应。理想的佐剂能够激发多种实验动物维持较高的抗体滴度 (即使使用少量抗原 ) ,可用于大部分抗原 ,容易制备 ,便于注射 ,少量即可奏效 ,免疫毒性低 ,对研究者没有危害。遗憾的是目前还没有完全符合上述标准的佐剂。选择佐剂原则上由研究者执行 ,但应首先考 Adjuvants can enhance the immune response. Ideal adjuvants stimulate many experimental animals to maintain high antibody titers (even with small amounts of antigen), are useful for most antigens, are easy to prepare, are easy to inject, are effective in small amounts, have low immunotoxicity, and are not harmful to researchers . Unfortunately, there is currently no adjuvant that fully meets the above criteria. The choice of adjuvant is in principle performed by the investigator, but should be tested first
