Recovery of analytes using combinatorial libraries

摘要

The invention provides a method of binding multiple targets in samples by binding to multiple ligands. The method comprises providing ligands attached to a support, and contacting the ligands with targets to produce at least two target-ligand-support complexes. The method further comprises removal of non-bound targets followed by elution of the bound targets. The eluted targets are present in concentrations of a particular analyte that is a function of their comparative concentrations in different samples. Furthermore, the mixture is enriched for trace components.
