    [Abstract] Current mass spectrometry (MS) methods and new instrumentation now allow for more accurate identification of proteins in low abundance than previous protein fractionation and identification methods. It was of interest if this method could serve to define the virus proteome of a membrane-containing virus. To evaluate the efficacy of mass spec to ...

    [Abstract] Chemical and sedimentation procedures are used to purify virus particles. While these approaches are successful for wild-type viruses, they are often not feasible for purifying mutant viruses with assembly defects. We combined two published methods (Atasheva et al., 2013; Moller-Tank et al., 2013), to generate a protocol that ...
