SDS-PAGE analysis of concentrated supernatants from positive transformant and the control. Lane 1: Concentrated supernatant of empty vector transformant as negative control. Lane 2: Non-concentrated supernatant of empty vector transformant as negative control. Lane 3: Protein marker. Lane 4: Concentrated supernatant of GS115 positive transformant culture after 4 days of induction. Lane 5: Non-concentrated supernatant of GS115 positive transformant culture after 4 days of induction. Black arrow shows the expressed urate oxidase.
