    摘要: It is an object of the present invention to provide a simple and efficient means capable of evaluating the VH/VL interaction without expressing/purifying VH and VL. The present invention provides a recombinant vector comprising: (i) a nucleotide sequence which can express a hetero-assembly composed of two types of fusion proteins wherein heavy chain variable region (VH) and light chain variable region (VL) of antibody are respectively fused with mutually associable first polypeptide and second polypeptide, by means of secretion, or in a form of a fusion protein tethered to a phage coat protein; and (ii) a restriction enzyme recognition sequence at two sites within, or in a vicinity of, a nucleotide sequence encoding said first polypeptide or second polypeptide.
