Site-specific labelling of proteins

Site-specific labelling of proteins

An in vivo method for labelling a protein having an N-terminal cysteine is disclosed. A probe comprising a thioester group and a detectable label is introduced into a cell expressing the N-terminal cysteine protein, allowing for the N-terminal cysteine to cleave the thioester bond and resulting in t...

Zusammenfassung:An in vivo method for labelling a protein having an N-terminal cysteine is disclosed. A probe comprising a thioester group and a detectable label is introduced into a cell expressing the N-terminal cysteine protein, allowing for the N-terminal cysteine to cleave the thioester bond and resulting in the label being covalently attached to the N-terminus of the protein by an amide bond.
