摘要:
A physiologically active polypeptide which has a lymphotoxin activity and is stable and resistant to decomposition-causing factors during purification and storage and which is substantially free of impurities. It is useful as an antitumour agent, and has the following sequence:

摘要:
Lymphotoxin-producing human T-cell hybridomas are incubated in a medium containing phorbol myristate acetate, concanavalin A or a mixture thereof, the resulting cells are fractionated by sucrose density gradient centrifugation method to isolate a messenger RNA in l2.6S to l4.6S fractions, and a gene containing a part encoding a polypeptide having a lymphotoxin-activity is prepared from the messenger RNA. The gene is represented by the base sequence of the Table l as herein given. Using the present gene, a new lymphotoxin having the amino acid sequence (I) or (II) as given herein can be obtained by genetic engineering technology.
