ADAM10 has been shown to be an effective α-secretase in vitro and in vivo. This enzyme acts as a sheddase to cleave cell surface proteins involved in neuropathology, inflammatory response and tumor progression.
The SensoLyte® 520 ADAM10 Activity Assay Kit is an optimized assay that can be used to detect the ADAM 10 activity. The unique FRET substrate contained in the kit was designed to reduce the cross reactivity with ADAM17 (also called tumor necrosis factor-α-converting enzyme, TACE). When active ADAM10 cleaves the FRET substrate, it results in an increase of 5-FAM fluorescence monitored at excitation/emission = 490/520 nm. The long wavelength fluorescence of 5-FAM is also less interfered by the autofluorescence of components in biological samples and test compounds. This assay can detect as low as 0.25 ng/mL active ADAM10.
The kit contains:
• 5-FAM/QXL® 520 ADAM10 substrate, Ex/Em=490/520 nm upon cleavage • Assay buffer • Recombinant human ADAM10 • Inhibitor • Fluorescence reference standard for calibration • A detailed protocol
