M Antigen and Potassium Types in Lambs

  • Elisabeth M. Tucker


Red cells from sheep foetuses and newborn lambs of the genotype Mm and MM react only weakly or not at all with the M reagent and yet have a high red cell potassium concentration. The red cells become fully M-positive at about the same time that adult red cell potassium levels are established and foetal haemoglobin has disappeared, that is, 40–50 days after birth.
