The second example of anti-M1 antibodies produced by a group MN person.
A second example of anti-M1 antibodies produced by a group MN person has been identified, and the reactions observed confirm the results obtained with the first example. The antibodies react with 17.2% of American black M positive samples. At 25-27 degrees C, the serum reacts strongly with untreated cells; the reactions are weaker with ficin-treated cells, but are enhanced with neuraminidase-treated cells. The antibodies are IgM; they were detected in ABO reverse grouping tests.
