Cypridina Luciferase (CLuc) is secreted from the marine ostracod, Cyridina noctiluca. As a reporter gene, its ultrasensitive bioluminescence activity can be measured in mammalian living cells or lysates. CLuc is a highly stable protein, even in high temperatures. CLuc uses a specific luciferin, (also known as Vargulin) which is not a substrate for Gaussia, firefly or Renilla luciferases. Therefore, Cypridina is compatible with other luciferases in dual activity assays. The combination of GLuc and CLuc reporter systems is ideal for assays at multiple time points from the same sample (1,2). An example of this, was published by a group studying the cycling activity of clock genes (3).CLuc bioluminescence has been used for sensitive antibody detection of tumors (4).
