Quantitative differential fixation of sulfate by tissues maintained in vitro.I. Sulfate fixation as a function of age for embryonic tissues

C H O N D R O I T I N sulfate is found in the mucoids of almost all of the tissues of the animal body. T h e greatest concentrations are in cartilage and bone matrix, but considerable quantities are found in the mucoids of the trachea, tendons, stomach, cornea, and probably in the seromucoid of the blood22 It has been suggested by Partridge that chondroitin sulfate may have an important role in the organization of collagen in the development of connective tissue.
