  • Patent number: 5840522
    Abstract: DNA sequences encoding full length precursor proteins, which proteins contain both A and B portions of two ricin isotoxins and ricin agglutinin, as well as the linker regions have been determined. These DNAs or portions or modifications thereof are expressed in recombinant hosts to obtain the desired proteins or proteins which can readily converted thereto. One of the ricin isotoxins may be related to ricin E.

  • Patent number: 5760203
    Abstract: Guanosine triphosphatase activating protein (GAP) DNA sequences are described that are useful as cancer diagnostics, particularly to detect cancer cells that express the ras oncogene protein p21 by measuring the level of GAP gene expression or amplification.

  • Patent number: 5725850
    Abstract: A colony stimulating factor, CSF-1, is a lymphokine useful in treating or preventing bacterial, viral or fungal infections, neoplasms, leukopenia, wounds, and in overcoming the immunosuppression induced by chemotherapy or resulting from other causes. CSF-1 is obtained in usable amounts by recombinant methods, including cloning and expression of the murine and human DNA sequences encoding this protein.
