Ac-LEHD-AFC is a synthetic peptide substrate commonly used in biochemical research. Here are some key applications of Ac-LEHD-AFC:

Apoptosis Research: Ac-LEHD-AFC is frequently used to monitor caspase-9 activity, a key enzyme involved in apoptotic pathways. By quantifying the fluorescence released upon cleavage of the substrate, researchers can assess the degree of apoptosis in cell samples. This helps in understanding the mechanisms of cell death and in screening potential anti-cancer drugs.

Enzyme Kinetics: This substrate is ideal for studying the kinetic properties of caspase-9. By performing enzyme assays with Ac-LEHD-AFC, scientists can determine parameters such as Km and Vmax, which are crucial for characterizing enzyme activity. These studies provide fundamental insights into enzyme function and regulation.

Drug Screening: Ac-LEHD-AFC is used in high-throughput screening assays to identify inhibitors of caspase-9. By observing the reduction in fluorescence, researchers can identify compounds that effectively block caspase-9 activity. This application is important for discovering new therapeutics for diseases where apoptosis plays a key role.

Toxicology Studies: In toxicology, Ac-LEHD-AFC is employed to evaluate the cytotoxic effects of various compounds and environmental agents. By measuring caspase-9 activation, researchers can infer the potential of a substance to induce apoptosis in target cells. This information is vital for risk assessment and regulatory compliance.
