Among the three studied NDDs and the healthy controls, both Hb and B3 protein were most stable in AD RBCs, the Tm difference of Hb between the fresh and aged ALS cells being ca. 0.5–0.6 °C, while the B3 protein stability was not changed up to day 40 of the aging process (Table 3). The gene discussed is GSTM1; the disease is Alzheimer disease.
