Applications: Monitor the JNK signaling pathway activity and AP1-mediated activity. Screen for activators or inhibitors of the JNK signaling pathway.
Background: The stress-activated protein kinase/c-jun N-terminal kinase (SAPK/JNK) family of proteins incluces mitogen-activated protein kinases (MAPKs) that are activated by stress, inflammatory cytokines, mitogens, oncogenes, and inducers of cell differentiation and morphogenesis. Upon activation of the SAPK/JNK pathway, MAP Kinase Kinases phosphorylate and activate JNKs. The activated JNKs translocate to the nucleus where they phosphorylate and activate transcription factors such as c-Jun. cJun then binds to the activator protein-1 (AP1) response element and induces AP1 transcription.
Biological Activity: This cell line is validated for its response to stimulation by Phorbol 12-Myristate 13-Acetate (PMA) and to treatment with inhibitors of the JNK signaling pathway.
Description: The AP-1 Reporter - HEK293 Cell Linee is designed for monitoring the activity of the JNK signaling pathway. The AP1 Reporter - HEK293 cell line contains a firefly luciferase gene under the control of AP1-responsive elements that are stably integrated into HEK293 cells.
Format: Aqueous solution containing DMSO
Host Cell Line: HEK293
Mycoplasma Testing: The cell line has been screened using the PCR-based Venor™GeM Mycoplasma Detection kit (Sigma Aldrich) to confirm the absence of Mycoplasma species.
Storage Stability: Store in liquid nitrogen immediately upon receipt.
Supplied As: Each vial contains ~1.5 X 10^6 cells in 1 ml of 10% DMSO.
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: BSL-2
