    摘要： 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.
