1. A method of determining the stoichiometry of protein components of a viral capsid of a viral particle, comprising:
- subjecting a sample of viral particles to hydrophilic interaction liquid chromatography (HILIC) to separate the protein components of the viral capsid of the viral particles;
determining the masses of protein components of the viral capsid to identify the protein components separated by HILIC;
determining the relative abundance of the protein components of the viral capsid from the HILIC separation, thereby determining the stoichiometry of protein components of a viral capsid of a viral particle.

19. A method of determining the heterogeneity of protein components in a capsid of a viral particle comprising:
-
subjecting the viral particle to hydrophilic interaction liquid chromatography (HILIC) to separate protein components of the viral particle capsid; determining the masses of protein components of the protein capsid; comparing the determined masses of the protein components of the viral particle capsid with theoretical masses, wherein a deviation of one or more of the masses of protein components of the viral particle capsid from the theoretical masses is indicative of capsid heterogeneity. - View Dependent Claims (20)
