Structural characterization of a protein adsorbed on aluminum hydroxide adjuvant in vaccine formulation

2D 15N 13C NCA a and NCO b spectra of ANSII-AlumOH (blue, left) and rehydrated freeze-dried ANSII (red, middle); a superposition of the two NCA and NCO spectra, respectively, is also displayed to help in the comparison (right). The spectra were acquired at ~290？K, MAS 14？kHz and 800？MH
