Abstract

The effect of freezing and low molecular cryoprotectants on the intensity of peroxidative processes in rat’s liver microsomes have been studied using chemiluminescence (CL) method. As cryoprotectants (CP) we used solutions of glycerol (Gl), 1,2-propane diol (1,2-PD) and DMSO, prepared on Tris-buffer within the concentration range from 5 to 40% (w/w). The values of spontaneous chemiluminescence (SCL), amplitude, H2O2 light sum and Fe2+-induced CL were noted to augment when the cryoprotectant content in microsome suspension was higher than 30% (w/w).
