Preparation and selection of cells for producing bispecific antibodies
Provided are compositions and methods for preparing a cell suitable for producing a bispecific antibody. A plurality of eukaryotic cells are incubated with an agent under conditions to allow the cells to arrest at G1/S phase. The agent is then removed from the cells and the cells are transfected with a first vector comprising a sequence encoding a first monovalent antigen-binding unit having specificity to a first antigen and a second vector comprising a sequence encoding a second monovalent antigen-binding unit having specificity to a second antigen. A cell is identified from the plurality of cells that expresses both the first and the second antigen-binding units.
