Abstract: A novel method for carrying out immunoassays is described. The method involves use of a biological ice nucleating agent as a label. In particular, the method involves use of ice nucleating bacteria, or ice nucleating components derived therefrom, as a label.
Abstract: Novel bacteria strains are described which are created by the introduction of DNA encoding for the production of chitinase, an enzyme capable of degrading chitin present in fungi and nematodes. The strains have utility in producing chitinase for the purpose of inhibiting plant pathogens.
Abstract: A method of testing a plant to determine the variable fluorescence of the plant, and instrumentation for carrying out the method, is described. The method has use in determining the extent to which a plant has been damaged by photoinhibitory stress, or is susceptible to damage by such stress.
