    摘要: Novel collagen mimics are disclosed with a tripeptide unit having the formula (Xaa-Yaa-Gly)n, where one of the positions Xaa or Yaa is a bulky, non-electron withdrawing proline derivative. By substituting a proline derivative at either the Xaa or Yaa position in the native collagen helix, the stability of the helix is increased due solely to steric effects relative to prior known collagen-related triple helices. Methods are also disclosed for making the novel collagen mimics.

    摘要: The present invention is a method for a covalent ligation of one or more molecules to one or more surfaces, that is site-specific and both rapid and high yielding. The covalent ligation to the surface is based on the reaction of an azide and a phosphinothioester to form an amide bond. The method of the invention is particularly well-suited to the immobilization of peptides, proteins or protein fragments to surfaces.

    摘要: Polymeric chelating agents and metal chelates, particularly those of lanthanide metals and more specifically those of Gd(III), useful as contrast agents in magnetic resonance imaging (MRI) for therapeutic and diagnostic applications as well as clinical and biomedical research applications. The polymeric chelates are generated using ring-opening metathesis polymerization (ROMP). Polymers can have multiple sites for functionalization allowing for the synthesis of multimodal and targeted contrast agents. Hydroxypyridonate (HOPO)-based chelating moieties are integrated into a ROMP-derived polymer. More specifically, the HOPO-based chelating moiety is integrated into a benzonorbornadiene unit that constitutes the backbone of the polymer. The ROMP-derived polymer chelators can comprise multiple metal ions, particularly Gd(III) ions, in polymers of varying lengths to provide a series of agents with controlled relaxivites. Polymer chelates include those that are water-soluble.

    摘要: This invention relates to methods and compositions for designing novel fluorescent proteins, preferably to a green fluorescent proteins (GFP). The engineered GFPs are modified by substituting negatively charged amino acids with positively charged amino acids on the exterior of the protein making the protein cell permeable. The ability of the engineered fluorescent proteins to permeate cells obviates the need for transfections, allowing these novel proteins to be used in numerous biological applications.
