Fluorogenic substrate for ADAM8 (kcat/Km = 1.0 x 105 M-1s-1), ADAM10 (6.2 x 103), ADAM12 (2.8 x 105), TACE (TNF-α converting enzyme, ADAM17) (4.3 x 105), and likely other ADAMs, especially those that cleave TNF-α type sequences. Also efficiently cleaved by MMP-1, MMP-2, MMP-3, MMP-8, MMP-9, MMP-13, and MMP-14. FAM fluorescence is quenched by the Dabcyl group until cleavage separates them. Ex.: 485nm, Em.: 530nm. This substrate is useful for inhibitor screening and kinetic analysis.
