CSF1R / SRE Reporter Kit (MAPK/ERK Signaling Pathway)

The CSF1R SRE Reporter Kit is designed for monitoring the activity of the CSF1R signaling pathway in cultured cells. The kit contains a transfection-ready vector for CSF1R and SRE luciferase reporter vector. Upon ligａnd binding, active CSF1R will initiate the MAPK/ERK signaling pathway, leading to expression of the SRE-controlled reporter. This reporter contains the firefly luciferase gene under the control of multimerized SRE responsive elements located upstream of a minimal promoter. The SRE reporter is premixed with a constitutively-expressing Renilla luciferase vector that 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 for determining pathway-specific effects and the background luciferase activity.
