Assignee: | Genetics Institute, Inc. (Cambridge, MA) |
Application Number: | 07/526,474 |
Patent Claims: | 1. An isolated DNA sequence that codes an expression for an amino acid sequence selected from the group consisting of:
(a) amino acid 21 through amino acid 199 of the primate sequence of FIG. 3; (b) amino acid 21 through amino acid 199 of the human sequence of FIG. 3; (c) amino acid 1 through amino acid 199 of the primate sequence of FIG. 3; and (d) amino acid 1 through amino acid 199 of the human sequence of FIG. 3. 2. An isolated DNA sequence that codes on expression for an amino acid sequence comprising amino acid 21 through amino acid 199 of the human sequence of FIG. 3. 3. A DNA sequence that codes on expression for an amino acid sequence comprising amino acid 1 through amino acid 199 of the human sequence of FIG. 3. 4. A plasmid vector comprising a DNA sequence of claim 1 or claim 2. 5. A cell transformed with a DNA sequence of claim 1 or claim 2 in operative association with an expression control sequence capable of directing replication and expression of said DNA sequence. 6. The cell according to claim 5 wherein the cell is a mammalian or bacterial cell. 7. A process for producing an IL-11 protein comprising culturing a cell of claim 5 in a suitable culture medium and isolating said I1-11 protein from said cell. |
