Product Description
D-Luciferin Free acid, potassium salt, and sodium salt *UltraPure Grade*D- Fluorescein ( D-Luciferin ) is luciferase ( Luciferase ) is a commonly used substrate, widely applied across the biotechnology field, particularly in in vivo live‑imaging techniques. Its mechanism of action involves ATP In the presence of luciferase, luciferin (the substrate) can be oxidized to emit light. When luciferin is in excess, the number of emitted photons is positively correlated with the concentration of luciferase (see the figure below). By introducing a gene encoding luciferase ( Luc After the plasmid is transfected into cells, it is introduced into experimental animals such as mice and rats; subsequently, luciferin is injected, and bioluminescence imaging is employed. BLI ) to detect changes in light intensity, thereby enabling real-time monitoring of disease progression or the therapeutic efficacy of drugs, among other applications. It can also be utilized… ATP The impact on this reaction system is indicated by changes in bioluminescence intensity, which serve as a proxy for energy levels or physiological parameters.
D- Fluorescein is also commonly used in in vitro studies, including luciferase and ATP Horizontal analysis; reporter gene assays; high-throughput sequencing and various contamination detection methods. Currently, three product formats are available on the market, D- Fluorescein (free acid), D- Sodium fluorescein, as well as D- Potassium fluorescein. The primary difference among these three products lies in their solubility characteristics. D- Fluorescein (free acid) exhibits very poor water solubility and low solubility in buffer systems, unless it is dissolved in a weak base such as… NaOH and KOH Solution. Soluble in methanol ( 10 mg/mL ) and DMSO ( 50 mg/mL ). However, in the forms of sodium salts and potassium salts D- Luciferin can dissolve very easily and rapidly in water or buffer solutions, making it convenient to use; the solvent is non‑toxic, which makes it particularly well suited for in vivo experiments. Once formulated as a liquid, these three products exhibit no substantial differences in most applications.
