title: Enzyme-linked immunosorbent assay (ELISA) for antibodies to human myelin and axolemma-enriched fractions.
abstract: The Enzyme-Linked Immunosorbent Assay (ELISA) is a well established procedure for antibody determination which has gained wide acceptance, particularly in diagnostic virology. We have adapted the method for use with the lipid rich antigens of human myelin and axolemma enriched fractions. Adsorption of the antigen onto the assay plates was rapid and relatively independent of pH. Antibodies to myelin and axolemma cross-reacted extensively. Little antibody reaction was noted using human liver microsomes, indicating the antibodies were specific but that myelin and axolemma shared at least one strong common antigen. With further purification of the antigen, this method should be useful in evaluating immunogenicity and antigenic purity of these membrane fractions.
