Estudio de la microviscosidad de la Hemoglobina A (HbA) y la Hemoglobina S (HbS) en condiciones de desoxigenación espontánea

Abstract

La microviscosidad de la hemoglobina A y la hemoglobina S es analizada en muestras con concentración intracelular, durante el proceso de desoxigenación espontánea y a 36 ºC, empleando glutatión y carbonmonoxihemoglobina, marcados con 4-maleimido-tempo. El glutatión marcado muestra un comportamiento constante de la microviscosidad de la hemoglobina S durante el estudio. La carbonmonoxihemoglobina marcada muestra un incremento de la microviscosidad durante el proceso de polimerización de la hemoglobina S, lo cual pudiera explicar el comportamiento de los tiempos de relajación magnética protónica determinados en otros artículos para las mismas muestras. Tanto el glutatión como la carbonmonoxihemoglobina marcados, reportan un comportamiento constante de la microviscosidad en la hemoglobina A.

The Microviscosity of hemoglobin A and hemoglobin S are analyzed in samples of intracellular concentration, during the free deoxygenation process and at 36 ºC, using Glutathione and Carbonmonoxihemoglobin labeled with 4-maleimido-tempo. Labeled Glutathione shows a constant behaviour of the hemoglobin S microviscosity during the study. Labeled Carbonmonoxihemoglobin shows an increase of the microviscosity during the hemoglobin S polymerization process, which could explain the proton relaxation times behaviour determined in other articles for the same samples. Labeled Glutathione and Carbonmoxihemoglobing report constant behaviour of microviscosity in hemoglobin A.
