Two kinds of mouse monoclonal antibodies which recognize distinct epitopes of the IL-2 receptor (a chain) were used to establish a sandwich ELISA for measuring soluble IL-2 receptors. The results indicated that this method is sensitive and specific for detecting soluble IL-2 receptors of cell culture supernatant and serum from both healthy donor and patients with leukemia. Therefore this sandwich ELISA method is useful for basic and clinic immunology research.

We obtained human lymphoblastoid B cells secreting human antibodies IgM and IgG to HFRS virus by Epstein-Barr virus(EBV)transfomation of PBMC.Conditioned media from the supernatant of a human fibroblast cell CRL1506 culture and irradiated CRL1506 cells as feeder cells could markedly promote the growth and antibody produotion of the human B lymphoblastoid cells at low cell density.It was shown that conditioned media contained a high level of interleukin 6(IL-6) .These results would be very useful for human monoclonal antibody technique including improving human B lymphoblastoid cell growth at low cell density and enhancing cloning efficiency andantibody production.
