    摘要: Purified cytotoxic proteins for use within therapeutic compositions are disclosed. The proteins inhibit protein synthesis in vitro, exhibit abortifacient activity in mice, and contain proline residues with equivalent positions at residue 43 and residue 46 in ricin A-chain. A method for preparing such a cytotoxic protein from the tissue of Trichosanthes kirilowii is also disclosed. The proteins may also be used within a method for inhibiting protein synthesis in selected cells.
