Resumo
This paper presents preliminary findings for a metallomics study of mercury in the muscle of the fish species from Amazonas, Brazil, after protein separation by two-dimensional polyacrylamide gel electrophoresis and subsequent evaluation of mercury by synchrotron radiation X-ray fluorescence. The fluorescence spectra revealed mercury in two protein spots. The mercury-containing protein spots showed molecular weights of 20.8 +/- 0.7 and 19.8 +/- 0.5 kDa and isoelectric points of 5.6 +/- 0.2 and 7.5 +/- 0.3, respectively.
