Research Use Only

The Notch1/CSL Transient Packis designed to provide the tools necessary for transiently transfecting and monitoring the activity of the Notch signaling pathway in HEK293 cultured cells. The kit contains transfection-ready vectors containing firefly luciferase as a Notch pathway-responsive reporter and constitutively expressing Renilla luciferase as a transfection control. 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 Notch1/CSL Transient Pack is the expression vector for NOTCH1 that has a deletion of the entire extracellular domain (Notch1DE). Inside the cells, the NOTCH1 DE can be cleaved by gamma-secretase and active NOTCH1 NICD is released into the nucleus. The kit also contains CSL (CBF1/RBP-Jk) luciferase reporter vector, which is a Notch pathway-responsive reporter. This reporter contains the firefly luciferase gene under the control of multimerized CSL responsive elements upstream of a minimal promoter. The CSL (CBF1/RBP-Jk) reporter is premixed with constitutively expressing Renilla (sea pansy) luciferase vector, which serves as an internal positive control for transfection efficiency. The pack 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 a firefly luciferase gene under the control of a minimal promoter, but without any additional response elements. The negative control is critical for determining pathway specific effects and background luciferase activity. Additionally, the pack includes cell culture medium (BPS Medium 1) that has been optimized for use with HEK293 cells*. BPS Medium 1 includes MEM medium, 10% fetal bovine serum, 1% non-essential amino acids, sodium pyruvate, and 1% Pen/Strep. Finally, the pack provides the Dual Luciferase (Firefly-Renilla) Assay System. These luciferase reagents provide highly sensitive, stable detection of firefly luciferase activity and Renilla luciferase activity. The dual luciferase reagents can be used directly in cells in growth medium, and can be detected with any luminometer; automated injectors are not required. *Note: the kit may be used with other cell lines than HEK293, but an alternate cell culture medium may be required for optimal cell growth,
