Abstract
Two monoclonal antibodies against staphylococcal lipoteichoic acid (LTA) were made by fusing P3X63Ag8 myeloma cells and splenocytes from mice immunized with purified LTA. Both were isotyped as being IgM kappa. Their specificities were determined by enzyme-linked immunosorbent assays indicating that both antibodies reacted with the glycerol-phosphate backbone, while one of them also had some affinity for the alanyl substituent. Antibodies in serum from 7 multiple sclerosis (MS) patients and serum and cerebrospinal fluid (CSF) from 7 non-MS patients apparently reacted with the sugar moiety of LTA. In contrast, CSF antibodies from 6 of the 7 MS patients and 1 of the 7 non-MS patients had affinity for the alanine residue. This non-MS patient also had serum antibodies against the alanine residue. None of the other sera tested appeared to contain such antibodies.
