Spherical influenza virion

A spherical influenza virion is an orderly hodgepodge comprised of hundreds of proteins that originate from both the virus and its host. A new mass spectrometry analysis, published in Nature Communications, has yielded the most complete picture to date of the identities, arrangements, and ratios of proteins in influenza virions.

To sort out the virion components, researchers used sensitive mass spectrometry. Comparing the intensities of ion spectra among protein fragments allowed them to quantify the relative abundance of each protein.
