Although the use of two separate vectors for the expression of heavy chain and light chain has been reported, this approach has serious shortcomings such as the possibility of the integration of the two vectors in different genomic sites and the variation of the copy number for each gene which can in turn cause an improper ratio of the expressed light chain to heavy chain, and reduce the possibility of achieving cell clones with high expression level of active antibody.
