| Résumé : |
The design of a capillary viscometer for semi automated assay of collagenase activity is described. The rate of flow of a solution of a soluble derivative of collagen undergoing hydrolysis by the collagenase is measured "continuously" by an electronic flow meter. Since the reciprocal of the flow-rate is proportional to the viscosity and the latter is a (double exponential decay) function of the collagenase concentration (as well as of time), collagenase concentration can be determined from the flowrate at a given incubation time. The data are collected automatically, stored in a computer, and analyzed at the analyst's convenience. The viscometer is suitable for use in research laboratories investigating damage to hides (and therefore to leather) caused by bacterial digestion of collagen. |
