title: Antibodies that define NANA-independent MN-system antigens.
abstract: The hemagglutinating properties of a large proportion of anti-M and anti-N reagents, and sera containing antibodies to MN-related antigens, have been shown to be unaffected by treatment of red blood cells with neuraminidase. These antibodies, which define NANA-independent MN-system structures, provide further evidence that MN blood group specificity may also be determined by moieties other than N-acetylneuraminic acid.
