  • Monoclonal antibody recognizing alpha 2.fwdarw.3 bonds
    Patent number: 5141864
    Abstract: A hybridoma capable of producing a monoclonal antibody specific to a sialic acid containing glycolipid carrying N-acetylneuraminic acid residue having alpha 2.fwdarw.3 linkage is herein disclosed. The hybridoma can be generated by fusing (i) B cells or lymphocytes obtained by immunizing an animal with a sialic acid containing glycolipid carrying N-acetylneuraminic acid residue having alpha 2.fwdarw.3 linkage and (ii) myeloma cells.
