Abstract
Deoxygenated sickle cells (HbS) have been shown to orient in homogeneous magnetic fields because of magnetic anisotropy of the hemes. The time of rotation is proportional to 1/H2 and is in agreement with theory. Structural information concerning the orientation of HbS molecules in the fibers is obtained from these experiments and is shown to agree substantially with existing models.
摘要
由于血红素的磁各向异性，已证明脱氧镰状细胞（HbS）在均匀磁场中会发生取向。旋转时间与1/H²成正比，且与理论相符。从这些实验中获得了有关纤维中HbS分子取向的结构信息，结果表明与现有模型基本一致。
