title: A pH-dependent auto-agglutinin with anti-P specificity.
abstract: An agglutinin with apparent anti-P specificity, reactive only at pH values below 6.0, was found in the plasma of a healthy female blood donor. It is postulated that this agglutinin recognizes latent receptors revealed by structural alterations to red blood cell membranes which occur in an acid environment.
