Abstract

The present invention is related to an isolated polypeptide micro-scaffold displaying immunoglobulin CDR2 or CDR3 polypeptide sequences, comprising a CDR2 or CDR3 polypeptide sequence interconnecting fragments of the adjacent framework polypeptide sequences, which are arranged to form two anti-parallel β-strands. The present invention is further related to a method to search, select or screen for immunoglobulin CDR2 or CDR3 polypeptide sequences that bind to a given antigen or mixture of antigens, comprising the steps of: Creating a CDR library with the method of claim 13 from the genetic information of an individual or group of individuals; Select a CDR, which binds to said antigen or mixture of antigens.
