Mammalian VLPs associated viral and cellular proteins identified by mass spectrometry (LC/MS/MS).

aExcised protein bands were numbered as indicated by arrows 1–11 of Fig. 4A and C.bFor this search a Mascot score ≥25 is significant (p>0.05).cSequence coverage is based on peptides with unique sequence.dViral and cellular proteins have been reported in influenza virion [26].*The band number, Mascot score, and sequence coverage of cellular proteins both identified in H5N1- and H3N2-VLPs were signalized as A/B.$The band number, Mascot score, and sequence coverage of single protein distributed in multiple locations was presented as A, B.
