title: Anti-keyhole limpet hemocyanin antibody in normal unsensitized individuals.
abstract: Antibody to keyhole limpet hemocyanin (KLH) has been detected in normal unimmunized subjects by means of a sensitive micropassive hemagglutination technique. Prior sensitization was not detected by either skin testing or lymphocyte transformation. After immunization with KLH there was no correlation between the level of this antibody and subsequently acquired skin test reactivity and lymphocyte transformation.
