Simulation of the natural abundance isotopes for the formula C109980 H173340 N29700 O34200 S720 was carried out using Bruker Xmass software version 4.0 (Bruker Daltonics, Billerica), assuming a resolving power of 5000 and using a Fourier transform algorithm.21

To obtain the mass of the virus capsid 50 acquisitions were signal averaged and a mean smoothing algorithm applied (2 × 25) (MassLynx version 3.2). The spectrum was imported into Win-IR (Bio-Rad/Galactic Industries Co., Salem, NH) and fitted with a linear baseline. The charge states over the mass rangem/z20147−24152.7 were modeled with Gaussian distributions. Masses were calculated fromm/zvalues obtained for the center of the fitted peak. 21 consecutive Gausssian distributions were fitted with the exception of the peak betweenm/z23809.0 and 24152.7, which could not be determined with confidence. From the two highest intensity consecutivem/zvalues in Figure 1b (21346.2 and 21142.4) the charges on the ions were assigned initially as 105 and 104 by the solution of simultaneous equations.16Since this method does not take account of the difficulties in determiningm/zvalues of very large molecular weight species the charge on the peaks was iterated across the series and the results of this process are shown in the Supporting Information. 12 charges were assigned to eachm/zvalue and each series used to calculate the mass of the neutral molecule. The standard deviations of the 12 series showed that four charge state assignments had the lowest standard deviations, between 5010 and 5434, across the 21 peaks, Figure 2 and Supporting Information. From these four charge state assignments a value for the experimental mass was calculated as 2484700 ± 25200 Da. It is important to note that this mass was calculated from the peak tops of the highest charge states in the series and does not therefore take into account the natural asymmetry of the peaks and the increased counterions that bind to the lower charge states.
