Firefly-renilla dual luciferase assay kit

Luciferase assay is one of the most popular reporter assay system for quantitatively measuring the function of promoters and other cis-elements. The wide-ranging and quantitative detection is the prominent feature of this assay; light emmision from 10~(-18) ― 10~(-11) mol protein can be quantitatively measured using luminometer (see our results). A promoter or other cis-element to be analysed can be ligated above this part. Its effect will be measured as an altered firefly luciferase expression. Meanwhile, renilla luciferase expression can be used to as an internal control.

Calibration

For detailed data, see [http://2011.igem.org/Team:UT-Tokyo our page] and BBa_K518000.

Usage

We performed a test of this cassette using BBa_J23119 and BBa_R0011. We successfully verified the IPTG-dependence of BBa_R0011, and at the same time, the potency of this part as an evaluation tool. For experimental and analytical details, see [http://2011.igem.org/Team:UT-Tokyo our page].
