    Abstract: Populations of polypeptide variants based on a common scaffold, each polypeptide in the population comprising the scaffold amino acid sequence EXXXAXXEIX XLPNLTXXQX XAFIXKLXDD PSQSSELLSE AKKLNDSQ (SEQ ID NO: 1) or AKYAKEXXXAXX EIXXLPNLTX XQXXAFIXKL XDDPSQSSEL LSEAKKLNDS Q (SEQ ID NO: 2), wherein each X individually corresponds to an amino acid residue which is varied in the population are disclosed. Also populations of polynucleotides, wherein each member encodes a member of a polypeptide population are disclosed. Furthermore, combinations of such polypeptide populations and such polynucleotide populations are disclosed, wherein each member of polypeptide population is physically or spatially associated with the polynucleotide encoding that member via means for genotype-phenotype coupling.
