What is rluc?

Rluc is a type of protein used in biotechnology research, specifically in protein-protein interaction studies. It stands for Renilla luciferase, which is a form of luciferase enzyme found in the marine organism Renilla reniformis. Rluc emits light when it reacts with its substrate, coelenterazine, making it useful as a biological marker to study and monitor protein interactions. Rluc is often used in conjunction with another protein-protein interaction assay involving a different luciferase enzyme, such as firefly luciferase, to enable comparative analysis of interactions. Its use has resulted in several important discoveries in fields such as cancer research and drug development.
