Abstract
A monoclonal antibody A exhibits specificity to the sialic acid glycolipid containing the epitope NeuAc.alpha.2.fwdarw.9NeuAc terminal. A monoclonal antibody B exhibits specificity to the sialic acid glycolipid containing the epitope NeuAc.alpha.2.fwdarw.6Gal.beta. terminal. A monoclonal antibody C exhibits specificity to the sialic acid glycolipid containing at least one epitope selected from the group of NeuAc.alpha.2.fwdarw.9NeuAc terminal, NeuAc.alpha.2.fwdarw.6Gal.beta. terminal and NeuAc.alpha.2.fwdarw.1Cer. Hybridomas are prepared which produce antibodies A, B and C. A process for producing the hybridomas is disclosed including the step of fusing a myeloma cell and a B cell (lymphocyte) produced by the immunization of animal using as an antigen, the sialic acid glycolipid containing at least one epitope of the group NeuAc.alpha.2.fwdarw.9NeuAc terminal, NeuAc.alpha.2.fwdarw.6Gal.beta. terminal and NeuAc.alpha.2.fwdarw.1Cer.
