| Résumé : | Casein was tagged with radioactive iodine by a simple method. This was found to be a suitable substrate for the enzyme plasmin. The increase in radioactivity in the trichloroacetic acid filtrate from iodinated casein incubated with the enzyme was taken as a measure of proteolytic activity. The main advantages of the method are, first, that the substrate is completely devoid of plasminogen and, second, that the value of the blank and of the experimental readings depends solely on the substrate and not on the other reagents used. © 1959. |
