Reduced RBC survival in murine sickle cell anemia and thalassemia.
At t = 0, murine RBCs were biotinylated by tail vein injection of sulfo-NHS-biotin. At indicated time intervals, streptavidin labeling and flow cytometric analysis measured the number of biotinylated cells. Survival data were fitted to A(t) = A0[1−(t/T)]exp−kt, in which A(t) is the number of biotinylated RBCs at time (t), A0 is the initial number of biotinylated cells at t = 0, and T is the time of senescent death of RBCs. Data are depicted for 6 different sickle (SS) mice, 4 different β-thalassemic (β-thal) mice, and 3 different control (WT) mice.
