Quasi-elastic light scattering was used to detect the initial stage of aggregation of hemoglobin S solutions. Aggregation of a hemolysate upon deoxygenation was found to occur at concentrations above 11 g/dl, but purified hemoglobin S solutions showed evidence of aggregation only for concentrations greater than 14 g/dl. A transition from a nonaggregated to an aggregated state was observed when the oxygen pressure in solution was reduced below a critical value. The total intensity of the scattered light during the early stages of aggregation was found to increase linearly with time. This result is consistent with a linear association process in which any size aggregate can combine with any other size aggregate.
准弹性光散射被用于检测血红蛋白S溶液聚集的初始阶段。发现当浓度高于11 g/dl时,溶血产物在脱氧时会发生聚集,但纯化的血红蛋白S溶液仅在浓度大于14 g/dl时显示出聚集迹象。当溶液中的氧压降低到临界值以下时,观察到从非聚集状态到聚集状态的转变。发现在聚集早期散射光的总强度随时间线性增加。该结果与线性缔合过程一致,在该过程中任何大小的聚集体都可以与任何其他大小的聚集体结合。
