SR XRF analysis indicated the presence of copper in three protein spots of plasma, and in two protein spots of muscle and liver, respectively. Copper ions were found to be distributed mostly in proteins that had a molar mass of less than 54 kDa and greater than 13 kDa and a pI in the 5.3-9.3 range. The copper concentration bound to these proteins was determined by GFAAS which showed concentrations in the 1.20-4.82 mg g-1 range.493-498porNile tilapiametalloproteinsmetallomicsFracionamento de cobre em proteínas do plasma, músculo e fígado de tilápia do NiloCopper fractionation in proteins from plasma, muscle and liver of Nile tilapiaArtigo10.1590/S0100-40422012000300010S0100-40422012000300010WOS:000303071700010Acesso abertoS0100-40422012000300010.pdf698144863745639135891372643644560000-0003-4179-05740000-0001-7264-3396
