Аннотация: Effect of dimethyl sulfoxide (DMSO), a widespread biomedical agent, on spectral-luminescent characteristics of coelenteramide-containing fluorescent protein - discharged obelin - is investigated. Contributions of violet and blue-green spectral components to fluorescence of discharged obelin are elucidated and characterized at different photoexcitation energies. Dependences of these contributions on the DMSO concentration are presented. Spectral changes are related to the destructive effect of DMSO on fluorescent protein and decreasing efficiency of proton transfer to electronically excited states of fluorophore.
