The 520 MMP FRET Substrate I is a sensitive fluorogenic peptide specially designed for detecting Matrix Metalloproteinases (MMPs). Its unique FRET mechanism allows rapid enzymatic activity measurements, particularly for MMP-13. This substrate excels in research areas like cancer and apoptosis, offering a reliable way to quantify protease activity with clear fluorescent readouts, differentiate enzymatic activity, and ensure reliable results for scientific studies.
