Identified proteins of two different respiratory viruses from mixed samples. Mixture A contained H3N2 (BM1454) and RSV (BM1450). Mixture B contained H1N1 (BM1456) and hMPV (BM1460).

Total genome copy number of the tested influenza virus and RSV in a total sample volume subjected to LC–MS/MS analysis.
Identified virus.
An average sequence coverage (%) of the identified protein was calculated from two independent experiments. A protein was considered identified when the MASCOT score was ≥50 and when a minimum of three peptides with a score ≥20 was identified in the protein.
The starting concentration of hMPV was 100 times lower than that for influenza and RSV.
NP, nucleoprotein; M1, matrix protein; NS1, non-structural protein 1; HA, hemagglutinin; NA, neuraminidase; M2-1, matrix protein; F, fusion glycoprotein; P, phosphoprotein.
