Figure Lengend Snippet: Schema for construction of S100A8/A9 coexpression vector and their protein expression in E. coli. (A) Expression vector for S100A8 or S100A9 were reconstructed into coexpression vectors by PCR amplification of each open reading frame and then subcloned by recombinase reaction. (B) Recombinant protein expression by each plasmid DNA for pET21-S100A8 (Lane 1), pET21-S100A9 (Lane2), pET21-S100A8-S100A9 (Lane 3), and pET21-S100A9-S100A8 (Lane 4) were confirmed by SDS-PAGE. Gels were stained with Coomassie Brilliant Blue (CBB).
Article Snippet: The gene fragments encoding human S100A8 (Uniprot: P05109 ) and S100A9 (Uniprot: P06702 ) were prepared by GeneArt Strings DNA fragment gene synthesis service (Life Technologies) with the sequence optimized for E. coli protein expression.
