What is Dielectric Properties and Oxygenation of Hemoglobin about?

Dielectric properties of human and horse hemoglobin were studied at frequencies ranging from 20 kc./sec. to 7 illc./sec. The relative errors in the measurements were usually less thaii The experimental setup allowed ns variation and measurement of the degree of oxygenation of the protein and to determine its dielectric parameters. Our main conclusion is that it was not possible to find any variation of the dielectric increment for hemoglobin oxygenation levels of 25, 50,75, and loo%, approximately. This result is a t variance with some previous reports. We cannot give the reason for this discrepancy but discuss some possible explanations. The specific dielectric increment, Ae,/c, of human hemoglobin was shown to be significantly smaller than that of horse hemoglobin (0.28 against 0.32). This physical property is lowered with increasing ionic strength I: Ae,/c = 0.28 and 0.20 for I = and lov3, respectively (human protein). even for mildly conducting solutions (lO-3M KCI).
