  • Publication number: 20070141639
    Abstract: OCTN2 is consistently expressed at high levels in brain microvessel endothelial cells. Disclosed herein are assays for determining whether a test material/molecule is a substrate for, and/or is actively transported by, the OCTN2 transporter, and therefore a candidate substrate for crossing the blood brain barrier.

  • Patent number: 7229757
    Abstract: Icosahedral phage and collections thereof that display various compounds are provided. In some instances, the icosahedral phage include nucleic acid tags that serve to record a characteristic of the compound or compounds that are attached to the phage. A number of different methods for using the icosahedral phage to screen a library of compounds for a desired biological activity are also provided, especially assays for compounds that are substrates for receptor-mediated transport processes such as endocytosis and transcytosis.

  • Patent number: 7192720
    Abstract: Reagents and methods for detecting target proteins in a sample are provided. The reagents include a replicable genetic package, a protein displayed on an exterior surface of the package that is expressed from a heterologous nucleic acid borne by the package, and one or more antibodies complexed with the expressed protein and which have an open binding site for a target protein. Thus, a segment of the nucleic acid encodes for an epitope that is shared by the expressed polypeptide and the target protein. The reagents can be utilized individually or as part of a library or an array to bind target proteins within protein samples to form one or more complexes. By determining the sequence of the segment of the heterologous nucleic acid of a package within a complex, one can identify the target protein since the segment encodes for an epitope that is shared by the expressed and target proteins.
