Interleukin 23 (IL-23) is a heterodimeric pro-inflammatory cytokine that shares traits with IL-12. Both cytokines contain the p40 subunit which binds to the receptor chain IL-12Rβ1. However, the two cytokines exert distinct non-redundant biological functions. IL-23 has been implicated as an inflammation mediator in several autoimmune diseases, and has also been found to promote tumor growth. Therapeutic agents targeting both IL-12 and IL-23 cytokines are currently used to treat psoriasis and psoriatic arthritis, and related agents are in clinical testing for a variety of inflammatory disorders.


Why Choose the iLite® IL-23 Assay Ready Cells?

  • iLite technology employs the cells’ inherent signaling pathways – a true model of cellular events
  • Assay Ready Cells – no culturing required!
  • No protein tagging or labeling required
  • Short assay times
    • IL-23 inhibitor activity: 30min + 5h
    • Neutralizing antibodies: 30min + 30 min + 5h
  • Highly reproducible between batches
  • Normalization gene allows for consistent results
  • Adjusts for serum matrix effects and differences in cell number
  • Highly specific for IL-23, no cross-talk with IL-12


The Eagle Bio iLite Assay Ready Cells are designed for the specific detection of drug potency in serum/plasma as well as neutralizing antibodies. They utilize an assay technique called reporter gene assay ( RPG ) to analyze serum/plasma samples. The reporter genes utilized are encoded with a bioluminescent luciferase (Firefly luciferase). Different levels of luminescence detected from each reporter gene cell indicates levels of expression.

Key benefits of iLite® Assays:

  • Highly specific reporter gene cell lines
  • Very sensitive cell line responses (>10 fold inductions)
  • Assay Ready Cells – ready-to-use from the freezer, without culturing of cells
  • Assays within a workday (typically 4-7 hour assays)
  • Normalization gene, which eliminates unwanted matrix effects
