Fluorogenic substrate cleavage assay
WebFluorogenic Peptide Substrates In response to proteolytic cleavage, Fluorogenic Peptide Substrates emit a signal that can be measured using a fluorescence plate reader. Many substrates are available including those suitable for assessing the activity of Matrix Metalloproteinases (MMPs), Cathepsins, Kallikreins, Coagulation Factors, and more.
