Further Examples of the Lutheran Lu(-5) Blood Type

Another Antibody Related to the Lutheran Blood Group System (Much.)

“…In addition to the main antibodies, anti-Lua and anti-Lub, which define the Lutheran blood group system, and anti-LuaLub made by the rare Lu(a-b-) people of the recessive type [4], there is emerging a series of anti bodies, anti-Lu4, -5, -6, -7 and anti-Lu8 [1,2,5,6,9] which associate them selves with the Lutheran system by having the common property of not reacting with cell samples of the phenotype Lu(a-b-) while reacting with the vast majority of other samples. The makers of anti-Lu4 to 8 have so far all been of apparently normal Lu(a-b+) phenotypes but each antibody besides failing to react with Lu(a-b-) cells fails also to react with the Lu(a-b+) cells of its maker and sometimes with certain sibs of the maker: the various antibodies are distinguished from each other by reacting positively with the cells of the makers of the other numbered antibodies.…”
