(Z-IETD)2-Rh 110 (trifluoroacetate salt)

(Z-IETD)2-Rh 110 is a fluorogenic substrate for caspase-8. Upon enzymatic cleavage by caspase-8, rhodamine 110 (Cay-19061) is released and its fluorescence can be used to quantify caspase-8 activity. Rhodamine 110 displays excitation/emission maxima of 496/520 nm, respectively.Formal Name: (5S,5'S,8S,8'S,11S,11'S,14S,14'S)-14,14'-(((3-oxo-3H-spiro[isobenzofuran-1,9'-xanthene]-3',6'-diyl)bis(azanediyl))bis(carbonyl))bis(5-((S)-sec-butyl)-8-(2-carboxyethyl)-11-((R)-1-hydroxyethyl)-3,6,9,12-tetraoxo-1-phenyl-2-oxa-4,7,10,13-tetraazahexadecan-16-oic acid), trifluoroacetate salt.
