Micromolar Concentration Affinity Study on a Benchtop NMR Spectrometer with Secondary <sup>13</sup>C Labeled Hyperpolarized Ligands Open
Benchtop NMR is becoming an increasingly important tool, sometimes providing a simple and low-cost alternative to high-field NMR. The Achilles heel of NMR and even more critically of benchtop NMR is its limited sensitivity. However, when c…
