  • Compositions and methods for enhancing bioassay performance
    Patent number: 6773928
    Abstract: Compositions of matter and methods for enhancing bioassay performance are disclosed. More particularly, the composition of matter comprises a molecularly compact polymer-ligand conjugate capable of self-orienting on a surface to improve the orientation of the ligand/receptor binding domains within the bioassay at the nanoscopic level. In a preferred embodiment, the molecularly compact polymer comprises a dendrimer polymer such as a fifth generation polyamidoamine dendrimer having exterior surface hydroxyl and amine functional groups, and the ligand/receptor comprises an antibody or Fab.

  • Enhancing protein activity through nanoencapsulation
    Patent number: 6716450
    Abstract: Nanocapsules useful for encapsulating bioactive molecules such as proteins are disclosed. These nanocapsules are comprised of branched or hyperbranched polymers and copolymers and have a core-shell structure forming a pocket volume appropriate for complexing and retaining enzymes and other bioactive molecules. The nanoencapsulated bioactive molecule is stable in extreme temperatures and pH, soluble in aqueous or organic solvents, and can be lyophilized to a dry powder for long-term storage without loss of enzyme activity.
