The Pierce Cypridina-Firefly Luciferase Dual Assay Kit is a highly sensitive assay that allows for the simultaneous detection of Cypridina and Red Firefly luciferase activity. Cypridina luciferase acts as an experimental reporter with constitutively active red firefly as a normalization control. This reporter-and-control combination enables simultaneous monitoring of experimental reporter and control luciferase activities in a single-read assay without the need for two-step addition of substrate reagents or quenching. The assay working solution contains substrates for both luciferases, and the reactions occur simultaneously with flash-type kinetics. The resulting luminescent signals are spectrally resolvable using filters. In a single sample, researchers can assay transcriptional activity of regulatory elements, signal transduction pathways, and effects of activators or inhibitors.
Simultaneous – concurrent, filter-based, wavelength-separated detection of two luciferase activities
Sensitive – measure bright blue Cypridina and red firefly luciferase activities in the same sample
Fast – no quenching step required, unlike in traditional sequential dual assays
Multiplex – capable of quantitating two cellular activities in the same sample(s)
Cell lysis buffer, reaction buffer, and substrates Vargulin and D-luciferin
Cypridina and Red Firefly luciferase reporters; Filter sets in the ranges of 425 to 525nm for Cypridina Luc and 615 to 675nm for Red Firefly Luc. Luminometer or other instrument capable of monitoring luminescence, such as Thermo Scientific Luminoskan Ascent and Varioskan Flash Microplate Readers; Injector required for assessing more than 24 wells at a time.
Study two regulatory elements at the same time; Monitor two signaling pathways simultaneously; Enable studying more than one target per screen (e.g. off-target effects)
