<p>Chemiluminescent substrate for b-galactosidase</p>

<p>Water soluble substrate for firefly luciferase. Used for imaging the expression of the LUC marker gene and luciferase-fusion conjugates in living cells, tissues and organisms. Extensively utilized in reporter gene assays, immunoassays and hygiene monitoring. Endotoxin free product.</p>

<p>Luc-Enterococcus K is a conjugate of the bacterial luciferase enzyme and Enterococcus faecalis. It is used in food testing, environmental testing and diagnostics. Luc-Enterococcus K can be used as a replacement for the fluorogenic substrate luminol, which is difficult to handle because it has to be kept cold during use and is explosive. Luc-Enterococcus K produces light when it reacts with the chromogenic substrate luciferin, which can be stored at room temperature without degrading. The light produced by Luc-Enterococcus K is blue green in color, making it easy to detect with a camera or eye.</p>
