Expression Systems

Add your protein of interest to the growing bibliography of SUMO-expressed proteins!

Our SUMO-based expression system maximize the yield of soluble, functional proteins in E. coli, yeast, insect and mammalian cells. This system features SUMO functioning as both a chaperonin and as an initiator of protein folding to dramatically improve the solubility and level of expression of your protein of interest. Our desumoylases efficiently and precisely remove SUMO tags, releasing your protein with the desired N-terminal amino acid. Both the SUMO tags and the desumoylases have His6 tags making their subsequent removal fast and easy.

Enhanced Expression and Solubility Using SUMO vs. Other Commonly-used Fusion Tags

Figure legend. GDF8 （myostatin）, a secreted TGFβ family member and difficult-to-express protein, was expressed in E. coli either as a His6, Ub, SUMO, MBP, GST, TRX, or NUS A fusion. Protein fractions were resolved by SDS-PAGE and stained with Coomassie. Arrowheads indicate expected/observed positions of respective protein bands. Of all tags tested, SUMO was the only fusion tag that provided high-level expression of soluble protein.
