Effect of storage temperature on the activity of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glutathione S-transferase in rat liver and kidney homogenates.
The behavior of the catalytic activities of the enzymes superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase and glutathione reductase was tested in rat liver and kidney homogenates stored at 4, -20 and -70 degrees C and in corresponding tissue samples stored at -70 degrees C. The stabilities of enzymes were different for various enzymes and were dependent on the organ (liver, kidney) and the storage temperature. The storage temperature of -70 degrees C guaranteed the best stability and the five enzymes investigated were sufficiently stable in preserved tissue samples or in homogenates prepared with conventional mannit/sucrose homogenization solution. Under such conditions, these enzymes were stable over at least 4 or 1 weeks, respectively.
