The PathHunter NIK Checkpoint Signaling cell line is a stable, engineered cell line for use in studying drug candidates (small molecules or biologics) targeting signaling checkpoints. This cell line enables assessment of ligand (e.g. CD40, TWEAK) induced non-canonical NF-κB signaling via detection of NIK stabilization. This product uses EFC technology. The included cell line overexpresses ED-tagged NIK (NF-kappa-B Inducing Kinase) protein. Upon activation of NFκB signaling by a ligand or an antibody, NIK is stabilized, allowing detection of EFC signal when treated with exogenous EA. This stable modified cell line is provided as two vials of cryopreserved cells. For detailed product information, User Manual and datasheet, visit www.discoverx.com/checkpoint.
