Abstract
Details are given of a method of obtaining the sedimentation constant of material of too small a molecular wt. to form a clear sedimenting boundary in the ultracentrifuge. This method was applied to the study of the peptides obtained by partial degradation of insulin with performic acid. The diffusion constants of 2 fractions were also measured and estimates made of their molecular wts.Keywords
