TACE FRET Substrate I (DABCYL - Leu - Ala - Gln - Ala - Val - Arg - Ser - Ser - Ser - Arg - EDANS)
% Peak Area By HPLC ≥ 95%
TACE FRET substrate I is derived from the cleavage sequence of pro-TNFa recognized by TNFa-cleaving enzyme (TACE). TNFa is presumably shed from cell membranes by TNFa-cleaving enzyme (TACE). Incubation of the TACE substrate with recombinant human TACE gives a specific cleavage to restore the quenched fluorescence. The substrate is widely used to screen inhibitors of TNF-convertase.
