Abstract
THE sulphate exchange of chondroitin sulphuric acid can easily be studied in vitro in surviving slices of cartilage suspended in a Krebs–Ringer-bicarbonate solution containing 35S-labelled sulphate1,2. The influence of various factors on this reaction, which is of an enzymatic nature, has been studied in this department. In the course of the work, it was noted that small amounts of a liver homogenate added to the suspending medium produced a remarkable stimulation of the sulphate incorporation into chondroitin sulphuric acid. As reported in a preliminary paper3, this effect was found to be due to the presence in the liver of a thermostable, dialysable factor.
