The transformants of E. coli induced with IPTG were collected by centrifugation, washed with 50 mM acetate bu¡er (pH 5.5), and then suspended in the sample bu¡er. The lysate solution was subjected to SDS^PAGE. To detect esterases including lipases, the gel was soaked at room temperature in a solution containing 1-naphthylcaprylate instead of 1- naphthylacetate (Sigma) and Fast Red TR Salt (Aldrich), and the activity was visualized as a red band .
