23Na-NMR study of cation cotransport in human red blood cells.
Cacciafesta M, Marigliano V, Ferri C, Piccirillo G, Scuteri A, Guidoni L, Luciani AM, Rosi A, Viti V. Cacciafesta M, et al. Am J Physiol. 1992 May;262(5 Pt 1):C1292-6. doi: 10.1152/ajpcell.1992.262.5.C1292. Am J Physiol. 1992. PMID: 1590364
The NMR method proposed for the study of Na(+)-K+ cotransport is relatively simple and allows quick evaluation of cotransport Vmax values for a number of samples, being a good candidate for the study of this transport mechanism in the presence of different pathologi …
