Nucleotide aggregation in aqueous solution. A multicomponent self-diffusion study.


The self-aggregation of the mononucleotides (AMP, CMP, GMP and UMP) and caffeine up to their solubility limit in 2H2O has been monitored through self-diffusion measurements, using the Fourier transform NMR pulsed-gradient spin-echo self-diffusion technique. The data were iteratively fitted to a number of aggregation models. It was concluded that the best… (More)
