General description
Malaoxon is one of the major metabolites of malathion and a widely used insecticide in agriculture. Its mode of action includes DNA damage in human lymphocytes by the mechanism of oxidative action.
Application
Malaoxon may be used as a reference standard for the determination of malaoxon in plasma and urine samples of rat by high-performance liquid chromatography.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

In this study, we determined normal serum butyrylcholinesterase (BChE) and carboxylesterase (CbE) activities in Tupinambis merianae in order to obtain reference values for organophosphorus pesticide monitoring. Forty-two T. merianae individuals were grouped by sex and size to identify potential differences
