After fusion, a culture contains hybridoma cells, unfused lymphocytes and unfused tumour cells. The cells are then grown in a medium in which only hybridoma cells survive. Why is this medium used?
It increases the rate at which hybridoma cells divide.
It removes cells that cannot both divide and make antibody.
It causes the unfused lymphocytes to fuse with tumour cells.
It changes the antigen that the antibody is able to bind to.
