The invention provides a method for detecting a 146S
antigen in a foot-and-mouth
disease vaccine based on a
capillary electrophoresis method and application thereof. The method comprises the followingsteps of introducing a water-phase sample of the foot-and-mouth
disease vaccine into a capillary tube by adopting pressure sample introduction, carrying out electrophoretic separation, detecting andrecording a characteristic peak of a 146S
antigen in the water-phase sample, then integrating to obtain a
peak area of the characteristic peak, and then obtaining the concentration of the 146S antigenaccording to a quantitative
standard curve. The method provided by the invention can be used for quantitatively detecting multiple
serotype 146S antigens at the same time, can be used for detecting monovalent, bivalent or trivalent foot-and-mouth
disease vaccines, has the advantages of low sample size, high sensitivity, high detection speed and the like, has important significance for realizing rapid sampling inspection of market vaccines and improving the market detection efficiency, and meanwhile, has huge application value in the aspects of product research and development and quality supervision of multivalent foot-and-mouth disease vaccines.
