(S)-3-((6-acetylnaphthalen-2-yl)amino)-2-aminopropanoic acid compound with 2,2,2-trifluoroacetic acid (1:1)

L-ANAP is an unnatural amino acid with intrinsic fluorescence that can be genetically encoded into proteins.1 This technology allows incorporation of L-ANAP into virtually any site on a protein, providing a unique method for imaging biological processes in vivo.
