title: Identification of an erythrocyte component carrying the Duffy blood group Fya antigen.
abstract: The erythrocyte component carrying the Duffy blood group antigen Fya has been identified as a 35- to 43-kilodalton protein. The protein is degraded by proteases, chymotrypsin, and Pronase, which destroy its antigenicity on intact erythrocytes. Its unusual property of aggregating on being boiled in 5 percent sodium dodecyl sulfate with 5 percent 2-mercaptoethanol distinguishes it from other erythrocyte membrane proteins described to date.
