NF-kB Assay Kit
This Human NF-kB assay kit is an all-inclusive firefly luciferase reporter assay system that includes in addition to NF-kB Reporter Cells, optimized media for use during cell culture and in diluting user’s test samples, a positive control activator, Luciferase Detection Reagent, and a cell culture-ready assay plate.
INDIGO’s cell-based reporter assays allow scientists to detect any biological activity that their test samples may exert against a specific receptor present in the cell. They utilize firefly luciferase reporter gene technology which provides superior precision and sensitivity. Since the receptor binding controls the expression of the luciferase reporter gene, luciferase activity in the cells can be correlated directly with the activity of the receptor. The strength of an interaction of a chemical with the target receptor is quantified using a luminometer to measure the level of light emitted.

Fast, reproducible, easy-to-analyze results are only four steps away
Many luciferase reporter assays require the user to grow their own cells and take time to optimize the results. INDIGO’s reporter cells contain the receptor of interest and the luciferase reporter gene. Reporter cells have been optimized to provide extreme sensitivity to quantify even small changes in receptor activity. With INDIGO’s cell-based reporter assays, the process is as easy as Thaw, Feed, Dose, and Read.
NF-kB Reporter Cells
NF-kB Reporter Cells are prepared using INDIGO’s proprietary CryoMite™ process. This proprietary cryopreservation process, enables long-term preservation of our unique reporter cells, so we can ship our cryopreserved reporter cells and assay reagents to you via overnight delivery, for your immediate use. Or, you can store the assay kits at -80°C. Once thawed, reporter cells are ready for immediate use so there is no need to take time on intermediate spin-and-wash steps, viability determinations, or cell titer adjustments.
NF-kB Luciferase Reporter
INDIGO’s NF-kB assay kits feature a luciferase detection reagent specially formulated to provide stable light emission between 5 and 90+ minutes after initiating the luciferase reaction. Incorporating a 5-minute reaction-rest period ensures that light emission profiles attain maximal stability, thereby allowing assay plates to be processed in batch. By doing so, the signal output from all sample wells, from one plate to the next, may be directly compared within an experimental set.
Bulk assay reagents can be custom manufactured to accommodate any scale of HTS. Please inquire.
NF-kB Assay Services
The primary application of INDIGO’s cell-based NF-kB assays are to quantitatively assess the bioactivity of a test compound as an agonist (activator) or antagonist (inhibition of an agonist response) of NF-kB. Service assays include a positive control reference compound and ‘vehicle’ control for every experiment. A formal study report and all data files are provided to the client upon completion of the study.

NF-kB Background
NF-kB is a signal transduction dependent transcription factor.
INDIGO's Human NF-kB Reporter Assay System utilizes proprietary human cells that express NF-kB (nuclear factor kappa-light-chain enhancer of activated B Cells), and contain the luciferase reporter gene functionally linked to upstream NF-kB genetic response elements. Thus, quantifying changes in luciferase expression provides a sensitive surrogate measure of changes in the level of NF-kB activation.
This NF-kB reporter cell line is validated to provide a robust dose-dependent activation response when treated with TNFa, or the Protein Kinase C activator Phorbol 12-myristate 13-acetate (PMA). As such, the principle application of this assay system is in the screening of test samples to quantify any functional activities that they may exert to modulate, either induce or suppress, NF-kB activities.
