DMNPE-caged D-luciferin (D-Luciferin, 1-(4,5-dimethoxy-2-nitrophenyl)ethyl ester) is a D-luciferin ester derivative which can cross cell membranes efficiently.^1,2 Once inside the cells, the ester is continuously hydrolyzed to a supply of D-luciferin. Alternatively a burst of D-luciferin is generated by UV photolysis.<ul><li>Light yellow solid soluble in DMSO</li><li>Store at -20&deg;C and protect from light</li><li>C₂₁H₁₉N₃O₇S₂</li><li>MW: 489.52</li></ul>
