| | Time Resolved Fluorescence Resonance Energy Transfer (TR-FRET) Assay |
| Description: | Test Example 2: Potency of compounds were also measured using another fluorogenic substrate, TruPoint BACE1 Substrate Eu-CEVNLDAEFK-QSY 7 (SEQ ID NO:3) (AD0258, PerkinElmer, Boston Mass.). This substrate also has Swedish variant amino acids at the β-secretase cleavage site, with a fluorescent europium (Eu) chelate coupled to one end and a quencher of europium fluorescence (QSY7) coupled to the other end via lysine. If the sample contains BACE1 activity, the Eu chelate and the quencher will be separated as the substrate is cleaved. |
