Résumé : |
Hide powder azure (HPA) and azocoll (Az) were evaluated for their suitability as collagen-rich substitutes for casein in assaying for the proteolytic activity of bate. Optimum conditions were established and a recommended procedure is presented. Under these conditions, the proteolytic activity of bate can be evaluated using an incubation period of one minute. Commercially available HPA and Az of small particle size were both found to be suitable substrates, provided the prescribed conditions are carefully observed. Evaluation of a commercially available preparation of coarse Az indicated that it is less suitable as a substrate for the assay. |
