Screening with a 7-mer phage display peptide library, a panel of cell-targeting peptides for the murine microglial cell line, EOC 20, was recognized. A number of similar, but not identical, sets of sequences representing more than 75% of all the cell line-binding clones were identified. Comparative analysis indicated that motif S/(T) F T/(X) Y W is present(More)
Unfolding and subsequent aggregation of proteins is a common phenomenon that is linked to many human disorders. Misfolded hemoglobin is generally manifested in various autoimmune, infectious and inherited diseases. We isolated micrometer and submicrometer particles, termed proteons, from human and animal blood. Proteons lack nucleic acids but contain two(More)
We have developed a gene delivery system that utilizes a cell-binding helper phage preselected from a landscape phage display library, and a phagemid harboring a marker gene and all regulatory elements (origins of replication and promoter-enhancer cassettes) necessary for replication of the phagemid and expression of the marker gene in the targeted cell.(More)
Biosensors based on phage display-derived peptides as biorecognition molecules were used for the detection of cell surface cross-species markers in tissue homogenates. The peptide selected for murine myofibers was immobilized onto the surface of an acoustic wave sensor by biotin-streptavidin coupling. To detect peptide-receptor interaction, the sensors were(More)
Early diagnosis and effective treatment of malignant gliomas, which are heterogeneous brain tumors with variable expression of cell surface markers, are inhibited by the lack of means to characterize and target tumor-selective molecules. To create molecular profiles for RG2 rat glioma cells, we used phage display technology, an approach capable of producing(More)
Cell-binding ligands for RG2 rat glioma were identified in our recent study from a library of peptides that are displayed as fusion molecules on phage particles. Here, one of the phage clones was used to affinity purify those cell membrane components to which the displayed peptides bind. This phage clone, displaying the ELRGDSLP peptide, was shown to(More)
Muscle makes up the largest tissue volume of the body, yet its size makes muscle-specific therapy difficult. This becomes particularly relevant when approaches to gene therapy for inherited myopathies are evaluated. Thus, a mechanism to target constructs or pharmaceuticals to muscle following intravenous injection would be advantageous. By screening a(More)
Personalized medicine is critical for cancer patients, because (1) cancer is a highly heterogeneous disease with major molecular differences in the expression and distribution of tumor cell surface markers among patients with the same type and grade of cancer, (2) cellular mutations tend to accumulate as cancer progresses, further increasing tumor(More)
Patented signal analytic algorithms applied to hydrophobically transformed, numerical amino acid sequences have previously been used to design short, protein-targeted, L or D retro-inverso peptides. These peptides have demonstrated allosteric and/or indirect agonist effects on a variety of G-protein and tyrosine kinase coupled membrane receptors with 30% to(More)
