Biological Activity

Orange-red TAMRA-based fluorescent D-amino acid. Suitable for labeling peptidoglycans in live bacteria. Incorporated into bacterial cell walls during synthesis. Suitable for prolonged exposure due to red-shift photophysical properties. Suitable for dSTORM and reSTORM. Displays good water solubility, photostability and thermostability. Excitation/emission λ ~554/580 nm.

This product is supplied as a TFA salt, the stoichiometry of which is batch dependant. Please refer to the Certificate of Analysis to obtain the batch specific Net Product Content,
