Magnetic susceptibility of oxy- and carbonmonoxyhemoglobins.

Abstract
The room temperature magnetic susceptibilities of human and carp oxy- and carbonmonoxyhemoglobin solutions were measured in a 30-gauss (1 G = 10-4 T) field with a superconducting magnetometer. To within experimental uncertainty, the susceptibility was the same for both the oxy and carbonmonoxy forms, and salt concentration did not affect it. A variety of sample preparations were used; the iron chemical state was verified by Moessbauer spectroscopy. A value of -0.580 .+-. 0.010 .times. 10-6 cm-g-s (cgs) system was obtained for the mass susceptibility of the protein. the paramagnetism sometimes observed in oxyhemoglobin solutions was attributed to the presence of a small amount of the deoxy form.
