title: Change in the stability of tendon collagen during ageing in the reptile, Calotes versicolor. A brief note.
abstract: Age related changes in the digestibility of tendon collagen of the garden lizard, Calotes versicolor, were traced using type I collagenase from Clostridium histolyticum. Collagen from older lizards showed less susceptibility for collagenase digestion than the younger lizards suggesting increased number of cross-linkages comparable with mammals.
