Peptic-Tryptic Digestion of Rennet-Custards in Vitro

The Effect of Peptic and Tryptic Digestion on the Antigenicity of Trichinella Spiralis.

The tryptic digestion of S-aminoethylated ribonuclease.

The peptides produced by the tryptic digestion of S-aminoethylated bovine pancreatic ribonuclease support the generally accepted amino acid sequence for this enzyme and also demonstrate the usefulness as well as some special limitations of the aminoethylation procedure. The relative extents of hydrolysis at different peptide bonds were estimated from the yields of purified peptides. Under the c...

The peptic digestion of ribonuclease.

The nature of the final products resulting from the proteolysis of proteins is determined to a large degree by the conditions of temperature, time of incubation, and hydrogen ion concentration employed during digestion. Thus, Linderstrgm-Lang and Jacobsen (1) have demonstrated a two-phase digestive process in the case of the system, p-lactoglobulintrypsin, the initial phase preponderating at 0”...

peptic-tryptic digestion of gliadin in a manner different from mucosal homogenates of guinea-pig and normal adult human jejunum

The aetiological relationship of wheat gluten and gliadin, and some peptides obtained from them by peptic-tryptic digestion, to the clinical and small intestinal mucosal abnormalities of coeliac disease has been demonstrated in several studies (Dicke, 1950; Anderson, Frazer French, Gerrad, Sammons, and Smellie, 1952; Sheldon and Lawson, 1952; Dicke, Weijers, and van de Kamer, 1953; van de Kamer...

Tryptic digestion of spectrin in variants of hereditary elliptocytosis.

Spectrin, either in the form of unfractionated low ionic strength extracts of erythrocyte membranes or purified by chromatography on Sepharose (CL)4B, was subjected to tryptic digestion at 0 degrees C. Four patients, each with a different variant of hereditary elliptocytosis, were studied. In one patient, whose erythrocytes showed significant fragmentation on heating on 45 degrees C, such prepa...
