abstract

  • We have constructed a single vector system for the rapid conversion of recombinant Fabs into whole IgG1 antibodies and their expression in eukaryotic cells. This vector, named pFab-CMV, utilizes the same unique cloning sites present on the pComb3 phagemid thus allowing for the direct subcloning of light chains and heavy chain Fd regions. pFab-CMV also allows for the expression of recombinant Fabs in eukaryotic cells by removal of a cassette containing part of the hinge, CH2 and CH3 sequences. Stable cell lines are rapidly obtained with pFab-CMV by NEO selection without the need for co-transfection of heavy and light chain expressing vectors.
