pEXPR_BACE2

This experiment was based on Anaspec’s SensoLyte 520 β-Secretase Assay Kit. This commercial kit uses a FRET-based technique wherein biological samples are mixed with a proprietary solution containing a BACE2 mimic substrate. One terminal of this mimic substrate is conjugated to a fluorophore and the other terminal is conjugated to a fluorescence quencher. So proteolytic Bace2 activity causes cleavage of the proprietary substrate, which increases fluorescence due to separation of the fluorophore from the quencher. Relative Bace2 activity in biological samples can be assayed by measuring the intensity of the fluorophore emission and comparing to a standard curve.
