[Impedance frequency properties of rabbit whole blood cells]
1Institute of Physiology and Pharmacology, Medical School of Ningbo University, Ningbo 315211, China.
Objective:
To establish characteristic parameters of complex impedance spectrum of rabbit whole blood cells.
Methods:
The AC impedances of 30 blood samples from the 10 rabbits were measured with the Agilent 4294A impedance analyzer at frequency range of 0.01-100 MHz and its characteristic data were analyzed by the Bode plot, the Nyquist plot and the Nichols plot.
Results:
The impedance amplitude and phase angle of rabbit blood cells was frequency-dependent. The impedance spectrum of rabbit blood cells had two characteristic frequencies: the 1st one (f(C1)) was 2.58 MHz, the 2nd one (f(C2)) was 5.21 MHz.
Conclusion:
The frequency properties of whole blood cells can be obtained by the analysis of impedance spectrum.
