  1. </h3>Glycerol Stock
    • 900 µl over night culture in LB-liquid medium
    • 900 µl 50% sterile glycerol

    Glycerol is extremely viscous. Hence, use cut off tips to pipette. Glycerol stocks were vortexed to ensure uniformly mixture and shock frozen in N2 or dry ice. Then, cultures were stored at -80°C. Do NOT forget to fill in the according GMO S1 construction sheet!
