  • Patent number: 4518701
    Abstract: Methods are provided for reducing non-specific interference in competitive protein binding assays employing as the labeled reagent a fluorescent conjugate of a hydrophobic ligand conjugated to a fluorescer, which in turn is bound to a water soluble polysaccharide carrier ("fluorescer conjugate reagent"). In order to reduce non-specific interference from physiologic samples, the fluorescent reagent is combined with a lipid substituted neutral support, under conditions which provides two binding fractions: a first weakly binding fraction which is relatively free of non-specific interference in a competitive protein binding assay employing physiological fluids; and a second fraction, which more strongly binds to the lipid substituted support.

  • Patent number: 4487602
    Abstract: An injection device particularly suitable for the intraruminal injection of ruminants is described. The injection device is characterized by a needle carrying means and a needle actuation means, which are operatively coupled such that the needle actuation means permits movement of the needle carrying means from a retracted position to an extended position, wherein the needle is capable of piercing the rumen, only when the needle carrying means is in a preferred orientation (e.g. perpendicular) to the surface of the host animal at the injection site. The injection device is further characterized by a dose delivery actuation means which is responsive to the relative position of the needle carrying means and the needle actuation means such that the dose is delivered to the host animal only when the needle carrying means and the needle actuation means are in a preferred position relative to each other.
