Expressing vector for YebF-Myrosinase
Expressing vector has been constructed using pcold-1 backbone. We demonstrate western blotting to show the expression of myrosinase. Expressing vector harboring myrosinase gene is transformed into BL21 strain using chemical method. After incubating at 37℃ for 12h, CFU is inoculated to LB medium followed by 12h incubation. The culture is then diluted to OD600=0.2 and let grow to around 0.5. 1 mM IPTG is added to the culture to induce protein expression followed by 12h incubation. Cells are washed and collected, ready for western blotting. The molecular weight of protein myrosinase is 57.46 kDa.
