Signosis has developed Gaussia Luciferase Substrate for detecting gaussia luciferase activity in our secreted luciferase reporter product lines and other similar coelenterazine based luciferase products on the market. It is a simple and convenient all-in-one solution that does not require any preparation to use, while still being very stable at 4°C at least a month. This reagent produces a strong light signal that is comparable to competitors' substrates but at a more cost-effective price.
