Abstract:
Processes for quantifying an amount of functional groups immobilized on a solid support are described herein. The processes allow for determining whether sufficient functional groups are provided on a solid support for the attachment of a first binding pair member for the detection of a target analyte.
Abstract:
A binding pair for chromatographic separation or purification of a molecule of interest, where one binding member of the pair is an isomerizable organic molecule and the other binding member of the pair is an isomer-specific affinity agent bound to a molecule of interest. The binding pair associates and disassociates upon exposure to a binding agent, such as using light, decreased intensity of light, darkness, heat, stress, ions, an isomerizable affinity agent, change in pH, or a combination thereof.
Abstract:
A multilayer, fluorescently responsive material (FRM)-containing nanoparticle and compositions comprising such nanoparticles. The nanoparticles can be made using a layer-by-layer deposition method. The nanoparticles can be used in imaging methods such as, for example, cellular imaging methods.

Abstract:
The present invention relates to a surface discovery system comprising chemical compositions and high-throughput combinatorial synthesis methods for generating large numbers of diverse surface coatings on solid substrates. This surface discovery platform is built upon a fundamental chemical unit referred to as a synthon. Each synthon comprises at least three elements: a chemical backbone coating on the solid substrate that comprises a passive (P) constituent and an active (A) constituent; a spacer unit (S) separating the backbone from a functional group; and a functional group (F). Variation of these synthon elements allows generation of large libraries surface coatings with a broad range of molecular and macroscopic properties. Further the spectrum of surfaces provided by the invention permits optimization of the wide range of solid-phase applications that involve surface immobilization of molecules.
Abstract:
An antibody-fragment-immobilizing substrate includes a substrate and at least one set of antibody fragments, wherein antibody fragments of each set include at least two types of separate antibody fragments, the at least two types of separate antibody fragments include at least one type of labeled antibody fragment having a labeled site labeled with a luminescent substance and at least one type of acceptor antibody fragment having an acceptor site for accepting emission from the labeled antibody fragment, and the at least one type of labeled antibody fragment and the at least one type of acceptor antibody fragment are capable of cooperatively recognizing one type of antigen in combination and are independently immobilized on the substrate in a positional relationship that allows each of the antibody fragments in one set to bind to the same antigen.
