The STAT3 Reporter kit is designed for monitoring the activity of the STAT3 signaling pathway in cultured cells. The kit contains transfection-ready STAT3 luciferase reporter vector. This reporter contains a firefly luciferase gene under the control of STAT3-responsive element located upstream of a minimal promoter. The STAT3 reporter is premixed with constitutively expressing Renilla luciferase vector, which serves as an internal control for transfection efficiency.
The kit also includes a non-inducible firefly luciferase vector premixed with constitutively-expressing Renilla luciferase vector as a negative control. The non-inducible luciferase vector contains the firefly luciferase gene under the control of a minimal promoter, without any additional response elements. The negative control is critical to determining pathway-specific effects and background luciferase activity.
