Clinica Chimica Acta, 1969
Abstract A simple and rapid method for the determination of proteolytic activity is described. The method uses the nephelometric measurement of changes in substrate concentration. It is shown to be sensitive and accurate and may be useful in clinical situations.

A reactive aspartyl residue of pepsin
Biochemical and Biophysical Research Communications, 1968Abstract Recently it was reported ( Hamilton, Spona, and Crowell, 1967 ) that pepsin was inactivated by an equimolar amount of 1-diazo-4-phenylbutanone-2 (DPB). The results indicated that the reaction occurred at or near the active site of pepsin. In the present communication we report evidence indicating that DPB reacts with pepsin to form an ester ...

Pepsins—A chromatographic and kinetic comparison
Analytical Biochemistry, 1969Abstract A simplified procedure for the preparation of pepsin from porcine pepsinogen has been developed. Chromatographic and kinetic data indicate that this procedure yields a pepsin product identical with that obtained by the conventional method.

Bovine pepsinogen and pepsin. IV. A new method of purification of the pepsin
Biochimica et Biophysica Acta (BBA) - Enzymology, 1971A new purification procedure for bovine pepsin (EC 3.4.4.1) based on affinity chromatography, is more rapid, and gives a higher yield and activity than previous procedures. It may be used for purification of other pepsins and of pepsinogen. Pepsinogen is extracted from gastric mucosa, fractionated with ammonium sulfate, and activated to pepsin.

Pepsin as a Marker of Extraesophageal Reflux
Annals of Otology, Rhinology & Laryngology, 2010Diagnosis of extraesophageal reflux (EER) currently relies on tools designed for diagnosis of gastroesophageal reflux. Such tools lack the sensitivity and reproducibility to detect the less frequent and mildly acidic reflux associated with upper airway disease. Pepsin has been posited to be a reliable biological marker of EER. Our aim was to present a
