Kinetics of Yop expression in D. discoideum. (A) Expression of yopE was induced by removal of tetracycline (-Tet). At indicated time points (in hours), total RNA of 107 cells was separated on 1.2% agarose/6.6% formaldehyde gels, transferred onto a nylon membrane, and probed with DIG-labeled yopE. (B) Expression of GFP-Yop fusion proteins. Expression was induced by removal of tetracycline (-Tet). At indicated time points (in hours), total cell protein from 5 × 105 vegetative cells was separated on 15%polyacrylamide/0.1% SDS gels and blotted onto nitrocellulose. Blots were probed with a GFP-specific antibody.
