Determination of Polysaccharide Content and Molecular Size Distribution of A, C, Y, and W135 Group Meningococcal Polysaccharide Vaccine by Capillary Zone Electrophoresis

Determination of Polysaccharide Content and Molecular Size Distribution of A, C, Y, and W135 Group Meningococcal Polysaccharide Vaccine by Capillary Zone Electrophoresis

Abstract Objective To establish a capillary zone electrophoresis method to detect the polysaccharide content and molecular size distribution of A, C, Y, and W135 group meningococcal polysaccharide vaccines. Methods A capillary zone electrophoresis method was established to detect four types of polysaccharides, exploring the optimal separation voltage and temperature. The method characterizes the four polysaccharides … Read more
