Regis Technologies manufactures Coelenterazine for use in research applications including reporter gene assays, ELISA assays, detection of calcium ions, whole animal assays and other biochemical assays. We produce high purity Coelenterazine to ensure the highest signal, lowest background, highest reproducibility, and lowest sensitivity levels for your application. Our manufacturing capabilities enable us to supply you with the highest purity material for your short term and long term needs, and the flexibility to help you overcome any obstacles. Coelenterazine-H has a 10- to 2-fold higher luminescent intensity than that of native coelenterazine, making it a useful tool for measuring small changes in Calcium ion concentrations in in vitro studies. This makes Coelenterazine-H the choice for certain biological applications.
