We compared the effect of human endothelial cell culture supernatant (HECS), ESG (Ewing sarcoma growth factor), IL-6 (interleukin-6) and peritoneal macrophages on the recovery of hybridoma cells after fusion with respect to growth, stability and distribution of isotype variants. A selective growth of murine IgM-producing hybridoma cells was observed in the presence of HECS after cell fusion.
