Protected iptg induction
WebbUpon IPTG induction (10 µM), a prominent band corresponding in size to the PVY CP dsRNA (dsPVY) was detected in bacterial nucleic acid extracts by agarose gel analysis and confirmed by resistance to RNase A, an enzyme that specifically degrades single-stranded RNA at high salt conditions ( Figure 1 A). WebbIPTG (isopropylthio-β-galactoside) is an inducer of β-galactosidase activity in bacteria and is suitable for use with X-gal or bluo-gal to detect lac gene activity in cloning procedures. …
