New capillary gel electrophoresis method for fast and accurate identification and quantification of multiple viral proteins in influenza vaccines.

Current methods for the identification and/or quantification of viral proteins in influenza virus and virosome samples suffer from long analysis times, limited protein coverage and/or low accuracy and precision. We studied and optimized capillary gel electrophoresis (CGE) in order to achieve faster and enhanced characterization and quantification of viral proteins. Sample preparation as well the composition of the gel buffer was investigated in order to achieve adequate protein separation in relatively short times.
