1. A method, comprising:
- a) providing i) a population of template molecules, each template molecule encoding a nascent protein or protein fragment, and ii) at least one surface comprising forward and reverse PCR primers attached to said surface;
b) amplifying at least a portion of said population of template molecules so as to create amplified product attached to said surface;
c) generating nascent protein or protein fragment from said amplified product, said nascent protein or protein fragment comprising an affinity tag or first epitope, and d) capturing said nascent protein or protein fragment on said surface via a first ligand, said first ligand attached to said bead and reactive with said affinity tag or first epitope.

Abstract
Bead-ligand-nascent protein complexes, and method of creating and detecting a bead-ligand-nascent protein complexes, are described. PCR-amplified product which is attached to a surface, e.g. of a bead, is used to generate nascent protein, which in turn is captured on the bead and detected, e.g. by fluorescence.
