Cathepsin D and E FRET Substrate acetate (839730-93-7 Free base)

Cathepsin D and E FRET Substrate acetate is a fluorogenic substrate selectively cleaved by cathepsins D and E at the Phe-Phe amide bond, demonstrating no activity towards cathepsins B, H, or L. This specificity renders it essential for routine assays and mechanistic studies focusing on cathepsins E and D[1].
