Abstract

The invention relates to a polypeptide which can be isolated from thymus glands and has an action on the immunological system, and which has a molecular weight of 3,480, a UV absorption with a maximum at 205 to 210 nm and an isoelectric point of 3.95+0.15 and a specific aminoacid composition, the N-terminal, if appropriate, carrying an acyl group or an acylglycyl group, processes for its isolation and purification, its use, agents containing this polypeptide, and its cleavage products, their use and agents containing them.
