  • Immunoassay for detection of mutant P53 polypeptide in serum
    Patent number: 6083709
    Abstract: The invention provides a method for diagnosing in a subject a neoplastic condition which comprises (a) obtaining from the subject a sample of a biological fluid; and (b) detecting the presence in the sample of a mutant p53 polypeptide encoded by an activated p53 oncogene, the presence of the mutant p53 polypeptide in the sample indicating that the subject has the neoplastic condition.
    Type: Grant

  • High temperature evaporation inhibitor liquid
    Patent number: 5552087
    Abstract: The present invention provides a liquid evaporation inhibitor which is suitable for use in high temperature applications; e.g., above 70.degree. C. The evaporation inhibitor liquid comprises a mixture of an alkane, a non-volatile oil, preferably a vegetable oil and a surfactant. The alkane is present in the mixture in an amount sufficient to provide a density which promotes floating on an aqueous medium and to cover an aqueous medium. The non-volatile oil is present in the mixture in an amount sufficient to inhibit evaporation of the mixture at temperatures above 70.degree. C. The surfactant is present in the mixture in an amount sufficient to maximize the contact surface area between the evaporation inhibitor liquid and the aqueous medium.
