摘要: 目的 探究多肽类抗原在与弗氏完全佐剂乳化过程中不同的抗原溶剂(无菌水和PBS 缓冲溶液)对乳化效果的影响。方法 利用三通管连接双注射器的人工乳化器推拉法进行抗原乳化,采用滴水实验检测乳化效果。结果 以无菌水作为溶剂,乳化时间较长,乳化程度易于人工控制;以PBS 缓冲液作为溶剂,会在极短时间即形成稳定的“油包水”乳剂,但容易乳化过度。结论 多肽类抗原乳化过程中,不同抗原溶剂对乳化效果的影响有较大差异。

Abstract: Objective To study the effects of different solvents (sterile water and PBS buffer) on the polypeptide antigen’s emulsification. Methods Dissolved polypeptide antigen was completely emulsified with complete Freund’s adjuvant by the way of pull-and-push with an artificial blender connecting three-way pipe and two yringes. The effects of emulsified mixture were evaluated by water drip test. Results The emulsification time was longer and the procedure was easy to control by taking the sterile water as solvent. The stable water in oil emulsifier was formed in a short time by taking the PBS buffer as solvent, whereas it was easy to get over emulsified. Conclusion The effects of different solvents on the polypeptide antigen’s emulsification were different significantly.

Key words: complete Freund's adjuvant, polypeptide antigen, antigen solvent, emulsion affection
