Abstract

Disclosed herein is a stable preparation of human erythrocytes for use in reverse blood typing comprising erythrocytes hemolyzed by gradual hypotonic hemolysis using a sequence of aqueous hypotonic buffers to form stroma wherein the stroma cells are in the form of discoid bodies having the reticular membrane of the cell substantially intact. The stroma reagent has been found to be highly stable and antigenic in the sense that it contains blood group antigens (carried on the stroma cells), and can be admixed with human blood serum or plasma to determine the presence of hemologous blood group antibodies.
