Abstract
CONCENTRATED suspensions of rabbit white cells were prepared by the method described by Mudd, Lucké, McCutcheon and Strumia1. When obtained by this method, about 95 per cent of the cells are polymorphs. Microscopic examination and measurement of respiration showed that the cells were in a normal condition. The impedance measurements were made at 21.4°C. Suspensions having volume concentrations from 10 to 42 per cent, in buffered 0.95 per cent sodium chloride, were used and the resistivity R (ohm–cm.) and parallel capacity C (m F/cm.) were determined from 0.25 to 16,000 kilocycles per sec.2,3 The values of R and C, as functions of the frequency, are shown for a 42 per cent suspension in Fig. 1.
