Sample | P50 of RBCs (mmHg) | Hill Coefficient (n) | Rate constant of autooxidation of Hb (h−1) |
---|---|---|---|
HbS without TD-1 | 35.30 | 1.75 | 0.039 ± 0.01 |
HbS with TD-1 | 15.36 | 1.58 | 0.045 ± 0.02 |
HbA without TD-1 | 25.22 | 1.98 | 0.035 ± 0.02 |
HbA with TD-1 | 11.68 | 2.07 | 0.05 ± 0.01 |
Whole blood samples from a sickle cell patient and ethnically matched control (approximately 20% Hct) were incubated with TD-1 (2 mM) for 15 min in Hemox buffer, pH 7.4. The rate constant of autoxidation for HbS and HbA (n=3) were determined in 50mM phosphate buffer, pH 7.4.
