Prolume Purple or methoxy e-Coelenterazine (Me-O-e-CTZ) is a new synthetic analogue of e-Coelenterazine with an additional methoxy group quenching the emission maximum from 475 nm to 405 nm. Nanolight™ Technologies developed Prolume Purple. (US Patent 2013/057660)
Prolume Purple exhibits an up to 13-fold higher luminescence than CTZ400a (“deep blue C”).

Comparison to CTZ400a
Emission spec with Renilla Luciferases
The advantages of lyophilized luciferins are:
- pre-aliquoted in small amounts, fresh substrate for every set of experiments
- long shelf-life (packed under Argon)
The luciferin is shipped as filtered, lyophilized, batch controlled substrate
