Fmoc-Arg(Pbf)-13C6, 15N4-TCP-Resin

For the validation and quantification of protein markers and post-translational modifications, isotopically labeled peptides have been shown to be useful tools. Especially in the field of tryptic peptides, isotopically labeled arginine and lysine at the C-terminal end has opened up the field for quantitative mass spectrometry.

The same benefits and chemical stability as for TCP-resin is valid for these resins. Please inquire for other isotopically labeled amino acids preloaded on TCP resin.
