Lanthanide-based fluorogenic peptide substrate for the highly sensitive detection of thermolysin

Bioorg Med Chem Lett. 2009 Oct 1;19(19):5757-9. doi: 10.1016/j.bmcl.2009.07.152. Epub 2009 Aug 4.

Abstract

A new fluorogenic, lanthanide-based oligopeptide substrate for the detection of the zinc-dependent endoprotease thermolysin is described. Using time-resolved fluorescence measurement, a highly sensitive assay for thermolysin was developed with a 50pM detection limit (3.5fmol).
