Fig. 1From: A proteomic approach to the development of DIVA ELISA distinguishing pigs infected with Salmonella Typhimurium and pigs vaccinated with a Salmonella Typhimurium-based inactivated vaccineRecombinant proteins expressions. Coomassie-stained gels and western blots of SipB (a) and FliC-frag (b) proteins. Time scale expression is shown in hours post induction (0–5 h, ON - overnight). Arrows indicate the expected molecular weight of a product. Expression of other proteins can be found in Additional file 1: Figure S1Back to article page
