a Hyperpolarized HN-CON correlation spectrum of osteopontin detected in 55 s using hyperpolarized HDO, in ca. 98% deuterated buffer, with assignments of a few well-resolved residues. b conventional reference spectrum acquired in 10% deuterated buffer. c Overlay of the hyperpolarized spectrum (red) and the reference spectrum (black). d Hyperpolarized HN-CON correlation spectrum of OPN in the presence of 2 equivalents of heparin, with assignments of some well-resolved residues. (Signal intensities are tabulated in Supplementary Tables S2 and S3.)
