Top: CEST spectra recorded at 11.7 T of solutions containing 8.0 mM [Co(TPT)]2+ in 200 mM NaCl, and 40.0 mM MES, HEPES, or CHES at 37 °C and different pH. RF presaturation applied for 3 seconds, B1 = 24 μT at 37 °C. Bottom: Dependence of [Co(TPT)]2+ CEST intensity at 135 ppm, 37 °C, on pH of the solution.
