Abstract

Provided is a linker for both screening assessment of the candidate clones without using enzymes, and to provide an in vitro selection method using thereof. Also, provided is a high-speed photo-crosslinking linker for molecular interaction analysis and in vitro selection comprising a backbone and a side chain. The backbone comprises a solid-phase binding site located at the 5′ terminus for forming a bond with a solid-phase; a solid-phase cleavage site for releasing the entire solid-phase at the site; a side chain linking site for linking a side chain; a high-speed photo-crosslinking site for linking the backbone to mRNA having a sequence complementary thereof via photo-cros slinking; and a reverse transcription initiation region located adjacent to the side chain linking site at the 3′ terminus of the backbone. The side chain comprises a fluorescent label, a protein binding site located at the free terminus thereof; and a binding site with the backbone.
