Antiglobulin testing for CR1-related (Knops/McCoy/Swain-Langley/York) blood group antigens: negative and weak reactions are caused by variable expression of CR1.

Abstract excerpt

The Knops, McCoy, Swain-Langley and York antigens have recently been identified as being on complement receptor type 1 (CR1, CD35, C3b/C4b receptor). We examined the relationship between CR1 expression and the reactivity of the CR1-related blood group antigens with their specific antibodies. RBC from donors of selected phenotypes were tested by hemagglutination using two monoclonal antibodies to CR1, as well as...
