700.3-MHz one-dimensional ¹H NMR spectra of S. suis serotype 1/2 polysaccharides. A, native CPS in 33 mmol/liter phosphate buffer, pD 8.0, in D₂O at 42 °C. 40,960 complex data points were acquired with a digital resolution of 0.18 Hz/point and processed as for Fig. 2A. B, desialylated polysaccharide in D₂O at 56 °C. 40,960 complex data points were acquired with presaturation with a digital resolution of 0.17 Hz/point and processed as above.
