Hyperpolarized 129Xe NMR study of Xe adsorption on 142 mg of lyophilized soybean lipoxygenase (L-1) exposed to (a) 2.5 atm (at room temperature) and (b) 6.0 atm of hyperpolarized Xenon. At each pressure, spectra are shown for several different temperatures. The sample was thermally equilibrated for several minutes prior to recording the 110.7 MHz spectra in a single scan following a 45° pulse. The spectra have been normalized to the maximum intensity in each spectrum, and no correction has been applied to account for the loss of xenon spin magnetization by spin-lattice relaxation or rf pulses.
