Description: The PDE4D Transient Pack is designed to provide the tools necessary for transiently transfecting and for screening inhibitors of PDE4D7 in cultured HEK293 cells._x000D_The assay is based on transfecting cells with the CRE luciferase reporter. CRE reporter contains the firefly luciferase gene under the control of cAMP response element (CRE). Elevation of intracellular cAMP activates CRE binding protein (CREB) to bind CRE and induce the expression of luciferase. Forskolin is commonly used to raise the intracellular level of cAMP in cell physiology studies. When cells transiently transfected with CRE reporter are activated by forskolin, the intracellular level of cAMP is upregulated, which induces the expression of CRE luciferase reporter._x000D_However, when cells are co-transfected with PDE4D7 expression vector and CRE reporter, the level of forskolin-induced cAMP is reduced, resulting in lower expression level of luciferase. When cells are treated with PDE4D inhibitor to inhibit PDE4D7 activity, cAMP level is restored, resulting in higher luciferase activity. The PDE4D Transient Pack contains transfection-ready CRE luciferase reporter. This reporter contains transfection-ready vectors for PDE4D7 expression and a CRE vector containing firefly luciferase as a cAMP pathway-responsive reporter and constitutively expressing Renilla luciferase as a transfection control._x000D_It also includes the Dual Luciferase detection reagents to detect both luciferase activities and specialized medium for growing and assaying HEK293 cells. The key to the PDE4D Cell-Based Activity Reporter Detection Valuepack is the CRE luciferase reporter vector, which is a cAMP/PKA Cell Signaling Pathway-responsive reporter. This reporter contains the firefly luciferase gene under the control of multimerized cAMP response elements (CRE) located upstream of a minimal promoter. The vector is premixed with constitutively-expressing Renilla (sea pansy) luciferase vector that serves as an internal control for transfection efficiency. The pack also includes the PDE4D7 expression vector, and the adenylate cyclase activator, forskolin. Additionally, the pack includes cell culture medium (BPS Medium 1) that has been optimized for use with HEK293 and HeLa cells*. BPS Medium 1 includes MEM medium, 10% fetal bovine serum, 1% non-essential amino acids, sodium pyruvate, and 1% Pen/Strep._x000D_Finally, the pack provides the Dual Luciferase (Firefly-Renilla) Assay System.
