  • Method of creating antibodies and compositions used for same
    Publication number: 20020068068
    Abstract: The present invention is directed towards compositions containing pathogenic bacteria (e.g. Haemophilus, E. Coli, and/or Salmonella) having non-reverting genetic mutations which alter activity of DNA adenine methylase (Dam) and methods using these compositions to elicit an immune response to produce highly specific antibodies. The invention also provides methods for preparing vaccines as well as screening methods to identify agents which may have anti-bacterial activity.

  • Catalyst for the isomerization of alkanes
    Patent number: 5017541
    Abstract: An improved catalyst particle is disclosed for the conversion of hydrocarbons which comprises a refractory inorganic-oxide support, a Friedel-Crafts metal halide, and a surface-layer platinum-group metal component, wherein the concentration of platinum-group metal component on the surface layer of each catalyst particle is at least 1.5 times the concentration in the central core of the catalyst particle. An isomerization process also is disclosed which is particularly effective for the conversion of C.sub.4 -C.sub.7 alkanes.
