1000K: pE-SUMOpro Kan Kit


In stock


The SUMOpro Protein and Peptide Expression Kit maximizes yields of soluble, untagged, functional proteins with the desired N-terminus. While other prokaryotic expression systems use engineered protease cleavage sites that produce amino acid extensions and often result in non-specific cleavage within the protein of interest, LifeSensors’ highly active and specific SUMO protease 1 recognizes the tertiary structure of the SUMO tag, generating the desired N-terminus and never cleaving within your protein of interest. In addition, the SUMOpro kit makes purifying your protein affordable and straightforward. By linking a His6 epitope to both the SUMO fusion tag and SUMO Protease 1, the SUMOpro system allows efficient and rapid purification of untagged protein using immobilized metal affinity chromatography.
