An embryo-specific pepsinogen was isolated from the proventriculi of 15-day-old chicken embryos and purified by means of fractionation with ammonium sulfate, filtration on Sephadex G-100, and chromatography on DEAE-Sepharose CL-6B and hydroxyapatite. The properties of this pepsinogen and pepsin derived from it were compared with those of an adult-specific chicken pepsinogen and its pepsin. Though the optimal pH and alkali-stability were similar in the two pepsinogens, molecular weight, sensitivity to pepstatin, and antigenicity were quite different. Among the properties of this embryo-specific pepsinogen, the large molecular weight (56,000 for pepsinogen and 53,000 for pepsin) is especially noteworthy, since the molecular weights of the known pepsinogens of mammals and birds fall into the range of 35,000-48,000.
