Expressing vector for YebF-Myrosinase

Expressing vector has been constructed using pcold-1 backbone. We demonstrated western blotting to show the expression of myrosinase. Expressing vector harboring myrosinase gene was transformed into BL21 strain using chemical method. After incubating at 37℃ for 12h, CFU was inoculated to LB medium followed by 12h incubation. The culture was 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 were washed and collected, ready for western blotting. The molecular weight of protein myrosinase is 57.46 kDa.
