Notes:
Positive and negative ion fast atom bombardment (FAB) mass spectra of the molecular ion region of calcitonin using several solution matrices produce an isotopic distribution which is indicative of a mixture of reduced and oxidized disulfide bonds. The insensitivity of the distribution to the choice of matrix and positive/negative ion mode suggest that the spectra reflect the natural abundance of reduced calcitonin in the sample, rather than an artifact of the fast atom bombardment technique.
