Happy TRAILs to you: PEGylation of proteins through complementary interactions between a His-tag and a Ni2+ complex of nitrilotriacetic acid (NTA, see picture), a well-established practice in protein research, was used to improve the half-life of therapeutic proteins in the blood following systemic administration in vivo. Animal models show that this site-specific modification improves the efficacy of modified TRAIL proteins.
Keywords: drug screening; histidine tags; PEGylation; protein design; protein modifications
