These hybridoma cells are then cult

These hybridoma cells are then cultured in vitro in selective
medium (i.e. medium containing hypoxanthine-aminopterinthymidine)
where only the hybridomas (i.e. the fusion between
the primary B-lymphocytes and myeloma cells) survive as they
have inherited immortality from the myeloma cells and selectiveresistance
from the primary B-lymphocytes (as the myeloma cells
lack HGPRT, they cannot synthesise nucleotides de novo as this is
inhibited by aminopterin in the selective medium)
