Observations on the Anton Antigen and Antibody

Abstract
Five [human] antisera with Anton specificity were studied serologically. The determinant was not sensitive to treatment by proteolytic enzymes (notably trypsin) and was present on cells of the recessive type of Lu(a-b-) phenotype. The Anton para-Lutheran antigen/antibody therefore seems to be associated with the Lutheran blood group system only by means of cells of the dominant type of the Lu(a-b-) phenotype which is controlled by In(Lu), a gene independent of the Lutheran locus.
