Figure 1. 31P NMR of high energy phosphates.
31P NMR spectra display relative high energy phosophate content in perfused hearts of non-transgenic littermates (NTG, left) and ssTnI expressing hearts of transgenic mice (TG-ssTnI, right). Piext, inorganic phosphate signal from extracellular buffer; Piint, intracellular inorganic phosphate; PCr, phosphocreatine; ATP, adenosine triphosphate groups.
