Fig. 4From: Use of an on/off tetracycline riboswitch to control protein production in Komagataella phaffiiβ-Galactosidase activity is reduced after exposure to tetracycline. The TRS Blue strain has shown to decrease protein production after 30 min of exposure in liquid media (n = 3). *Unpaired t-test shows that TRS Blue tc samples are significantly different from the other groups tested at a 95% confidence intervalBack to article page
