Direct immobilization and recovery of recombinant proteins from cell lysates by using EctP1-peptide as a short fusion tag for silica and titania supports

Immobilization of protein, compared to the use of free protein, offers improved stability, easy separation and continuous reusability. However, the classic routes for protein immobilization, based on non-specific adsorption, often negatively affect protein functionality. In this study, EctP1 peptide was explored as a novel short fusion tag for non-covalent adsorption on unmodified solid surfaces, silica and titania. A fusion of EctP1 with bovine...
