✦ Synopsis

010 C-13 and P-3 1 NMR Studies of 13CN-Cyanocobalamin in Sulfuric Acid-Water Mixtures Fig. 1. Crystais of horse heart ferritin grown from MPD (a), and from polyethylene gIyco1 (b). In both cases the longest dimensions of the crystals are approximately 0.15 mm.

The dimensions

of the heart ferritin crystals obtained so far are too slight to allow any crystallographic investigation.

All the crystals obtained are isotropic under the polarizing microscope, and thus belong to a cubic space group. This observation is in keeping with the molecular symmetry of the ferritin oligomer, which, in the case of the spleen protein, is coincident with crystallographic symmetry. Details of the crystalline forms isolated as well as of their growth solutions will be presented.
