Description

Packaging

5 g in poly bottle

Application

Alanine conjugated to the fluorophore 5-(dimethylamino)naphthalene-1-sulfonyl (dansyl). The unnatural amino acid has been incorporated into expressed proteins by use of a mutated aminoacyl-tRNA synthetase specific for dansylalanine.

Biochem/physiol Actions

Dansyl-L-alanine contains an N-terminal fluorophore (dansyl) making it useful as a fluorescent marker/probe. Dansylalanine can be incorporated into proteins by newly developing techniques that expand the genetic code.
