5-TAMRA Cadaverine TFA Salt
This product is a fluorescent probe combining 5-carboxytetramethylrhodamine (5-TAMRA), a cadaverine linker, and a TFA counterion. The TAMRA dye provides bright orange-red fluorescence, while the cadaverine amine enables conjugation to carboxyls or activated esters. The TFA salt specifically improves solubility and handling, making this probe useful for labeling and imaging.
