Rotation of sickle cells in homogeneous magnetic fields.

P C Riberiro, M A Davidovich, E Wajnberg, G Bemski, M Kischinevsky.   

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.
