Resumen:

The effects of anionic and cationic dendrimers as buffer additives on electropherograms of chicken sarcoplasmic proteins were examined. Starburst poly(amidoamine) dendrimers of generation G0 (cationic), 0.5, 1.5, 2.5 and 3.5 (anionic) were used in the concentration range of 10-5% to 1% g/ml. Anionic dendrimers, over the concentration range 10-5% to 0.1% g/ml, had a small effect on separation currents, which allows for tuning of selectivity and resolution over a wide range of dendrimer concentration with minimal contribution to buffer conductance and thus Joule heating. The resolution of protein electropherograms improved as a function of anionic dendrimer concentration and generation with a small effect on analysis times. A maximum of 10 components were identified in
