Fig 2. Homonuclear 800 MHz ¹H TOCSY spectra (exchangeable sidechain amide chemical shift region) of 22μM rSpSM30B/C-G and rSpSM50 hydrogel particle samples, 100 μM HEPES, pH 7.5.

Diagonal and off-diagonal regions for sidechain and backbone NH Arg, Asn, and Gln resonances are shown, along with corresponding 1-D spectra.
