Please note: This product will be discontinued on 12/31/2024

The pYSG-IBA43 vector allows the high-level expression of 6xHistidine/Strep-tag® -fusion-proteins in yeast. The vector carries the copper inducible promoter (CUP1) for controlled high-level expression, the 6xHistidine -tag for N-terminal and the Strep-tag® for C-terminal fusion of the recombinant protein as well as the URA3 auxotrophy marker for selection after transformation (do not use URA3 for selection during expression), the LEU2d auxotrophy marker for selection to increase plasmid copy number for expression (do not use LEU2d for selection after transformation). The expressed recombinant protein will be localized in the cytoplasm.
