title: Crystallization of one of the chicken pepinogens and its derived pepsin.
abstract: Dodecahedral crystals of chicken pepsinogen have been prepared, one perfect cystal having the dimensions 0.090mm x 0.086mm x 0.009mm.  The derived pepsin crystakkized in the form of flat plates, often with one rounded end.  The dimensions of one such crystal wer 0.076mm x 0.043mm.  Both types of protein crystals showed full enzymic or potential enzymic activity.
