iLite IL-12 Assay Ready Cells
iLite IL-12 Assay Ready Cells Developed and Manufactured by Svar Life Science
The Eagle Biosciences iLite® IL-12 Assay Ready Cells are intended for:
- Testing IL-12 or p40 inhibitor activity
- Testing NAb response against IL-12
For Research Use Only
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
Interleukin 12 (IL-12) is a 70 kDa cytokine produced principally by macrophages, neutrophils and dendritic cells in response to stimulation by antigen. IL-12 is a T cell-stimulating factor, playing a critical role in the regulation of T-helper 1 cell responses. IL-12 is composed of two subunits, p35 and p40, covalently linked by a single disulfide bond. The p40 subunit, which binds to the receptor chain IL-12Rβ1, is shared with another heterodimeric cytokine, IL-23. However, the two cytokines expert distinct non-redundant biological functions (1). 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 (2).
iLite® IL-12 ARCs are a genetically engineered reporter gene cell line (DT-40, ATCC#CRL-2111) responsive to Interleukin-12 by specific and proportional expression of Firefly Luciferase. Normalization of cell counts and serum matrix effects is obtained by a second reporter gene, a Renilla Luciferase reporter gene construct, under the control of a constitutive promotor.
