title: Intrinsic fluorescence of some myxo- and paramyxoviruses and of their subviral fractions.
abstract: Fluorescence spectra of Sendai and influenza A(H1N1) viruses have different emission maxima; their quantum yield is much lower than that of tobacco mosaic virus. Solubilized envelopes and nucleoproteins of Sendai, influenza and mumps virus have different half-bandwidth and relative quantum yield values of emission, according to the agent used for disruption. Thus emission (as well as excitation and absorption) spectra of Triton X-100-solubilized envelopes show a marked hypsochromic shift as compared with the envelopes obtained by Tween20-disruption. The results are correlated with the different disruption extent achieved with the two agents.
