 AB    Anti-galactocerebroside (GalC) antibodies have been reported to inhibit
       myelin formation, cause demyelination, and block HIV-I infection of
       neural cells. We examined the binding of 3 monoclonal and polyclonal
       anti-GalC antibodies to a panel of purified glycolipids by ELISA and by
       an immunospot assay on nitrocellulose blots. All 3 antibodies bound
       strongly to GM1 ganglioside, monogalactosyl diglyceride, and asialo-GM1,
       and 2 of the antibodies bound to GD1b and psychosine. The anti-GalC
       antibodies also bound to 3 glycoprotein bands in human neuroblastoma
       cells on Western blot, and binding to the proteins was abolished by
       pre-treatment with pronase or with periodate which oxidizes the terminal
       carbohydrate residues. These results indicate that anti-GalC antibodies
       cross react with oligosaccharide determinants of other glycolipids and
       glycoproteins, and that these cross-reactivities may be responsible for
       some of the biological effects of the anti-GalC antibodies.
