Peroxidase isozyme was analyzed by method of Polyacrylamide Gel Electrophoresis(PAGE) in Oryciolagus cuniculus(Chinese albino rabbit),New Zealand Rabbit,Rex Rabbit s blood serum.
Seven isozymes were analyzed by means of horizontal sliceable starch gel electrophoresis.Then further analysis of selected esterase(EST)was carried out on polyacrylamide gel electrophoresis(PAGE).
The results of biochemical analysis indicated that the difference of the activity of carboxylesterase and esterase isozymes in the larval midguts were the main mechanism of this selective toxicity.
