The invention provides a method for producing a defined population of binding molecules, said method comprises at 5 least the following steps: a) providing a population of B cells expressing a limited VL repertoire wherein essentially all of said B cells carry at least one VL, b) obtaining nucleic acids (RNA or DNA) from said B cells, c) optionally, amplification of nucleic acid sequences encoding immunoglobulin heavy chain variable regions in said sample, d) at least partial sequencing of all obtained nucleic acids of step b) or the amplification products of step c), e) 0 performing a frequency analysis of sequences from step d), f) selecting desired VH sequences, g) providing a host cell with at least one vector comprising at least one of said desired VH sequences and/or at least one VL sequence of said limited VL repertoire, h) culturing said host cells and allowing for expression of VH and/or VL polypeptides, i) obtaining said binding molecules.
