A column of immobilized antibodies directed against pure human pancreatic carboxylic (cholesterol) ester hydrolase was used to purify in a single step the enzyme from human pancreatic juice as well as carboxylic-ester hydrolases from other species (rat, dog). This immunoaffinity method was also used for the purification of the related bile-salt-stimulated(More)
Size exclusion high-performance liquid chromatography analysis was carried out on wheat gluten-glycerol blends subjected to different heat treatments. The elution profiles were analyzed in order to follow the solubility loss of protein fractions with specific molecular size. Owing to the known biochemical changes involved during the heat denaturation of(More)
Assembly of glutenin polymers was examined for two contrasted durum wheat cultivars in connection with changes in the redox status of the endosperm cells that accompanied grain development. The evolutions of the redox state of ascorbate and glutathione, as well as the activities of antioxidant enzymes were measured. Changes in the size distribution profile(More)
