lymphotoxin, but actually nukleinsaeure, nukleinsaeure containing vectors and transformed cells, method of lymphotoxin and lymphotoxin neutralizing antikoerper.

摘要

Lymphotoxin (I) absolutely free from homologous proteins that are unidentified or present in unknown amounts is new. Unglycosylated (I) is new. Variant (I) in which an amino acid residue in the (I) sequence has been deleted or substd. by another residue, or in which another residue has been inserted, is new. Provided that (I) having a sequence with an amino terminal at Leu(+)1 or His(+)23 is excluded. Nucleic acid encoding (I) and selected from (a)-(c) is new. (a) DNA encoding (I) free from DNA encoding other proteins of the organism from which the DNA originated; (b) DNA encoding (I) free from untranslated intervening sequences; and (c) nucleic acid capable of hybridising to nucleic acid encoding (I), provided that the acid does not have the nucleotide sequence of natural DNA or RNA encoding (I).
