In this system, the N-terminal segment of an engineered split intein is expressed in E. coli and covalently immobilized onto a capture resin, while the smaller C-terminal intein segment is fused to the N-terminus of the …
NettetIntegrity of the purified proteins was assessed via SDS-PAGE and Coomassie staining (for details see Figure S12, Supporting Information). The pure protein was concentrated using Vivaspin Ultracentrifugation filters with a molecular weight cutoff of 10 kDa. For use in SAXS measurements, protein solutions were dialyzed to HEPES pH 7.4 (5% Glycine). Nettet1. mar. 2012 · Highlights Ubiquitin-intein and SUMO2-intein fusion tags were constructed. Both tags enhance the expression of eGFP and solubility of eGFP and MMP13. Both tags allowed convenient purification of eGFP with high homogeneity. Both tags may present viable alternatives for protein production in industry process.
