Fig. 1From: Improving the thermostability and stress tolerance of an archaeon hyperthermophilic superoxide dismutase by fusion with a unique N-terminal domainSchematic illustration of rSOD Ss construction (a) and SDS-PAGE analysis of purified SOD Ss and rSOD Ss (b). Proteins were stained with Coomassie brilliant blue R-250. Ladder, standard protein size marker. The expected sizes of SOD Ss and rSOD Ss were 24.2 and 51.6 kDa, respectivelyBack to article page
