Coelenterazine (1 mg) is a luminescent substrate, laboratory grade, commonly used in bioluminescence assays. This substrate is employed in molecular biology research for the detection and quantification of luciferase activity. Coelenterazine is a substrate for the luciferase enzyme, resulting in light emission when it is metabolized. This reagent is widely used in assays to study gene expression, protein interaction, and various biochemical reactions in cells. It is particularly useful in luminescent reporter assays for tracking cellular processes, drug screening, and biotechnological applications that require precise measurements of biological activity.
