Open the CIPO recordAbstract From the Canadian patent
Thymosin is produced by an improved process in which thymus glands are coarse ground, extracted in saline solution which is filtered and the filtrate or extract is injected with steam for a brief period of time to denature undesired proteins without denaturing the thymosin, whereby a precipitate is formed which is separated by filtration. The filtrate is concentrated and cooled and crude thymosin is precipitated by adding the concentrate to acetone.
