Claims
- 1. The process of producing carcinoembryonic antigen (CEA) in vitro, comprising culturing cells selected from the cell lines consisting of LS-180 (ATCC No. CL-187), LS-174T (ATCC No. CL-188), and CEA-producing cells derived therefrom, in a nutrient medium capable of supporting the growth of said cells until the number of cells present have at least doubled, and recovering the CEA thus produced.
- 2. The process of claim 1 in which said cells are from the cell line LS-180 (ATCC No. CL-187).
- 3. The process of claim 1 in which said cells are from the cell line LS-174T (ATCC No. CL-188).
- 4. The process of claim 1 in which said cells are a trypsinized form of the cell line LS-180 (ATCC No. CL-187).
- 5. The process of claim 1 in which said cells are cloned cells derived from the cell line LS-180 (ATCC No. CL-187).
