BIPODAL PEPTIDE BINDER

摘要

The present invention deals with a bipodal peptide binder that specifically binds with a target including (a) a structure stabilizing region that includes parallel, antiparallel or parallel and antiparallel amino acid strands wherein interstrand non-covalent bonds are formed; and (b) a target binding region I and a target binding region II that are bonded at both terminals of said structure stabilizing region and respectively include n and m amino acids, and a method of preparing same; the bipodal peptide binder of the present invention exhibits the KD value (dissociation constant) of a very low level (for example, nM level) and, therefore, exhibits very high affinity toward a target. The bipodal peptide binder of the present invention has applications not only in pharmaceuticals but also in in-vivo imaging, in vitro cell imaging, and drug delivery targeting, and can be very usefully employed as an escort molecule.
