A plasmid expression vector for monitoring NfκB activation via luciferase in mammalian cells.

This high copy number eukaryotic vector, pTA-NfκB-Luc Luciferase Reporter Vector expresses a mutant luciferase gene under the control of the minimal TA promoter with the cis-element for NfκB upstream. When NfκB is activated, it binds to cis-element causing the induction of luciferase gene expression. Luciferase activity is directly representative of NfκB activity. This luciferase encoded by this vector is a mutant enzyme that catalyzes the production of long wavelength (red) light (Em: 605) from D-Luciferin, Product M0237. This mutant luciferase is optimized for expression in mammalian cells, resulting in drastically improved light production, allowing detection of expression at extremely low levels. The mutant luciferase also has been shown to remain stable at 37°C over long time periods, a characteristic not seen in wild type luciferases The mutant luciferase enzyme expression is enhanced by the Kozak’s consensus sequence and SV40 late polyadenylation signal.
