Desnaturação de oxihemoglobinas humanas A, A2 e S pelo metodo de tampão isopropanol
(1978-12-01)
Human oxyhaemoglobin A and A2 from normal individuals and oxyhaemoglobin S from patients with sickle cell anaemia and sickle cell trait were studied using Isopropanol/buffer method at 37°C and 40°C. Hb S was less stable ...
The water effect on allosteric regulation of hemoglobin probed in water glucose and water glycine solutions
(Amer Soc Biochemistry Molecular Biology Inc, 1996-03-01)
We have previously proposed a role of hydration in the allosteric control of hemoglobin based on the effect of varying concentrations of polyols and polyethers on the human hemoglobin oxygen affinity and on the solution ...

Urea-induced unfolding of Glossoscolex paulistus hemoglobin, in oxy- and cyanomet-forms: A dissociation model
(2013-01-01)
The urea effect on the giant extracellular hemoglobin of Glossoscolex paulistus (HbGp) stability was studied by analytical ultracentrifugation (AUC) and small angle X-ray scattering (SAXS). AUC data show that the sedimentation ...
Thermal denaturation and aggregation of hemoglobin of Glossoscolex paulistus in acid and neutral media
(2013-03-01)
The thermal denaturation and aggregation of the HbGp, in the oxy- and cyanomet-forms, was investigated by DSC, AUC, DLS, optical absorption and CD, in the pH range from 5.0 to 7.0. Oxy-HbGp has a denaturation process ...
