Substrati fluorogenici

Fluorescein-dipalmitoylphosphatidylethanolamine triethylammonium salt is a fluorescent phospholipid derivative for phospholipase. This substrate consists of a fluorescein conjugated to DPPE (dipalmitoylphosphatidylethanolamine), a key component of biological membranes. This compound is frequently used in membrane dynamics studies and lipid metabolism research. The fluorescein moiety allows visualization of lipid interactions in model membranes, liposomes, or live-cell imaging applications. The triethylammonium salt form enhances solubility and stability, property that facilitates its use in aqueous and lipid-based environments.

This Clips-O substrate 7-((4'-L-Alaninamido)-rac-3'-hydroxybutyloxy) coumarin allows the detection of single and dual enzymatic activity (L-alanine aminopetidase and oxidation of 4-amino-3-hydroxybutyloxy spacer either enzymatically or by exposure to sodium periodate) with a single substrate resulting in a fluorescent signal. The main virtues of Clips-O substrates are an increased stability towards non-enzymatic hydrolysis that results in a reduced background and high sensitivity.
