Purified Staphylococcus aureus capsular polysaccharide was prepared by a process consisting of extraction with Cetavlon and cold phenol, precipitation by ethanol, centrifugation, and so on, then analyzed by biological and immunological methods, detect the physicochemical characteristic and immunogenicity of it.
采用Cetavlon、冷酚、不同浓度乙醇沉淀、离心等步骤精制的荚膜多糖，用生物学、免疫学等方法分析检测其理化特性及免疫原性。
