Simultaneous Measurement of Glucose and O2 Consumption in Cell Suspensions with Minielectrodes
Separation procedures which yield cell suspensions with homogeneous cell populations greatly facilitate the study of cell metabolism, but yield a limited amount of material. Multiple recording of metabolic parameters from minimum volumes is therefore useful. We have developed a method for the simultaneous recording of glucose and O2 concentrations with Polarographic electrodes in 0.26 ml suspensions of rabbit epididymal spermatozoa (RES). These cells are found “pre-separated” as a homogeneous population in the cauda epididymidis. They consume glucose and O2 and produce lactate (Murdoch and White, 1967) and so provide a useful system to test the method as well as a system in which to study the effect of perturbations on aerobic glycolysis.
