WebSep 2, 2010 · Although the Lu (a) antigen is a poor immunogen, and anti-Lua is usually very weak compared to toher antibodies, it is comparatively common (often, without any known stimulus), and the antigen is quite frequent (about 5% in the Black population and about 8% in the White) and so cross-matching can be a problem; but transfusion is not. WebThe MNS blood group system contains 43 antigens, the major antigens being M, N, S, s and U while the others are low-frequency antigens resulting from either amino acid substitutions or rearrangements between GYPAand GYPB. The M and N antigens are located on glycophorin A (GYPA) while the S and s antigens are located on glycophorin B (GYPB).

WebThe original Lutheran antibody, later designated 2 Anti-Lu a, was described by Callender and Race 3, 4 in 1946. Anti-Lu a defines the antigen Lu a which is inherited as a Mendelian dominant character. 4, 5 The long wait for anti-Lu b to show itself is not surprising in view of the extremely low frequency of the genotype LuaLua. Webantigens within the BGS, but certain antigens (for example, Lu10) appear to be missing. This is the result of so-called para-Lutheran antigens, reported as possibly belonging to the Lutheran BGS but later proved to belong elsewhere.
