Abstract: Presented herein are methods, systems, and apparatus for single analyte detection or multiplexed analyte detection based on amplified luminescent proximity homogeneous assay (“alpha”) technology, but using hollow polymer fiber optics doped with ‘acceptor bead’ dye (e.g., thioxene, anthracene, rubrene, and/or lanthanide chelates) or ‘donor bead’ dye (e.g., phthalocyanine) that carry a signal generated by the dopant via singlet oxygen channeling.

Abstract: The invention provides methods for isolating a target molecule from a sample. In an embodiment, the method involves contacting a sample with a capture agent, the agent comprising a siderophore and a transition metal cation, under conditions wherein the agent is capable of binding a target molecule to form a target molecule-capture agent complex, wherein the target molecule is selected from the group consisting of a phosphorylated molecule, a nitrotyrosine-containing molecule and a sulfated molecule, and separating the target molecule-capture agent complex from the sample, thereby isolating the target molecule from the sample. Also provided are methods for determining the presence of a target molecule in a sample, that involve contacting a sample with a capture agent, the agent comprising a siderophore and a transition metal cation.
