    摘要: 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.

    摘要: 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.

    摘要: A conjugate of a modified randomly branched asymmetric polymer without a core and a member of a binding pair is described. The modified randomly branched asymmetric polymer can contain chain branches, terminal branches or both. The modified randomly branched asymmetric polymer can contain random asymmetric branches or random asymmetric junctions. The binding pair can be an antibody, antigen or a ligand. The conjugate includes a drug.
