Figure 4. Detection of VSV proteins by mass spectrometry.

(a) Mean spectral counts per technical replicate for VSV encoded proteins detected in both whole virions and proteinase K (ProK) treated virions. (b) Location of VSV G protein peptides identified in both whole and ProK treated virions as indicated by shaded boxes. Values given below the diagrams indicate the mean spectral counts per technical replicate for the indicated domain(s) with the overall percent sequence coverage given in parentheses.
