Abstract: The present invention is directed to novel methods for enhancing the ability to separate a species of interest from other different species present in a free solution mixture thereof which takes advantage of interactions that occur between soluble, small molecular weight ligands and the species of interest. The small molecular weight ligands employed in the present invention function to interact with a species of interest in a mixture of different species through either affinity, hydrophobic and/or ionic interactions, thereby altering the molecular weight, hydrodynamic volume and/or isoelectric point of the species of interest and rendering it separable from other component(s) in the mixture.

Abstract: The present invention provides an inexpensive and sensitive device and method for detecting and quantifying analytes present in a medium. The device comprises a metalized film upon which is printed a specific, predetermined pattern of analyte-specific receptors.

Abstract: A two-dimensional patterning of a three-dimensional surface by a template molecule (or object) involving non-covalent interactions between the template and the surface and the reversible fixation of the pattern by undergoing a phase transition in the patterned material. In this invention the surface provides a multitude of mobile functional groups (matrix) which are spatially arranged by the interaction with the template, the template selects and arranges only those groups out of a multitude of functional groups which allow for a maximum of interaction between the template and the surface. The resulting pattern is then stabilized by reducing the mobility of all functional groups present on the surface by undergoing a phase transition to a state of high surface viscosity. After separation of the template and the patterned surface, the pattern on the surface is used for recognition, separation or catalytic purposes.

Abstract: Cyanine and related dyes, such as merocyanine, styryl and oxonol dyes, are strongly light-absorbing and highly luminescent. Cyanine and related dyes having functional groups make them reactive with amine, hydroxy and sulfhydryl groups are covalently attached to proteins, nucleic acids, carbohydrates, sugars, cells and combinations thereof, and other biological and nonbiological materials, to make these materials fluorescent so that they can be detected. The labeled materials can then be used in assays employing excitation light sources and luminescence detectors. For example, fluorescent cyanine and related dyes can be attached to amine, hydroxy or sulfhydryl groups of avidin and to antibodies and to lectins. Thereupon, avidin labeled with cyanine type dyes can be used to quantify biotinylated materials and antibodies conjugated with cyanine-type dyes can be used to detect and measure antigens and haptens. In addition, cyanine-conjugated lectins can be used to detect specific carbohydrate groups.

Abstract: The present invention describes peptides capable of specifically binding to preselected micromolecules or to their natural receptor. The preselected molecules include but are not limited to drugs, vitamins, neuromediators and steroid hormones. Methods of using the phage display libraries to identify peptide compositions in preselected binding interactions are also disclosed. The retrieved peptides mimicking a natural receptor binding site to preselected molecules are used as is or as ligands to re-screen the same or different libraries to find and/or derive new receptor ligands, or are used to elicit the production of antibodies capable of binding to the natural receptor. The two categories of effector molecules (peptides or antibodies) may find diagnostic, therapeutic or prophylactic uses. The peptides directly derived from the phage display libraries may be used as drug detectors or antidotes.

Abstract: Pharmaceutical compositions with heretofore unknown and enhanced physical, chemical, and biological properties are prepared by combining known biologically active parent compounds with oxo thia azabicyclo compounds, such as lactam and .beta.-lactam compounds, capable of rapidly transporting the parent compounds in undegraded form to their target sites of action. A process for combining the parent compound with .beta.-lactam compounds consists of dissolving the parent compound in a polar solvent, adding a .beta.-lactam compound, incubating the resulting mixture, followed by drying, and subjecting the remaining solid material to solvent washing or extraction to further purify the new pharmaceutical composition. The new pharmaceutical composition possesses the biological and therapeutic activity of the parent compound and the barrier penetrating characteristics of the .beta.
