サイトカインシグナルを活性化または阻害するバイオロジックスの能力を測定

インターロイキン23(IL-23)は、IL-12、IL-23、IL-27、IL-35 およびIL-39で構成されるIL-12サイトカインファミリーのメンバーです。IL-23は、ヘテロ二量体の受容体複合体を介して結合およびシグナル伝達します。IL-23受容体は、ナチュラルキラー細胞、マクロファージ、メモリーT細胞(Th17)およびケラチノサイトに見られます。微生物病原体および創傷治癒シグナルに応じて、活性化された樹状細胞およびマクロファージにより IL-23が分泌され、好中球が補充がされます。IL-23がTh17細胞に結合すると、シグナル伝達はIL-12Rβ1へのチロシンキナーゼ2(TYK2)のリクルートとIL-23Rへのヤヌスキナーゼ2(JAK2)のリクルートより開始されます。これらのキナーゼは、シグナル伝達物質および転写活性化因子3(STAT3)をリン酸化および活性化し、一部 STAT4、STAT1およびSTAT5も活性化します。

IL-23バイオアッセイは、IL-23の刺激または阻害を測定するために設計された生物発光細胞ベースのアッセイです。IL-23バイオアッセイ細胞は、IL-23シグナル伝達に応答してluc2Pを発現するように設計されています。IL-23がIL-23バイオアッセイ細胞に結合すると、受容体は細胞内シグナルを伝達し、発光します。生物発光シグナルは、Bio-Glo™ Reagentを使用して検出および定量されます。

Assay Components

IL-23 Bioassay Cells are provided in a thaw-and-use format as cryopreserved cells that can be thawed, plated and used in an assay without the need for cell propagation (Cat.# JA2511, JA2515).

IL-23 Bioassay Cells are also available in a Cell Propagation Model (CPM) format, as cryopreserved cells that can be thawed, propagated and banked for long-term use (Cat.# J3002).

Workflow

Standardized Reagents Improve Results

  • Thaw-and-use format provides significant time and labor savings over traditional methods while reducing variability.
  • Kit includes all of the required reagents in standardized formats.
  • Easily amenable to high-throughput workflows.

Assay Principle

IL-23 Bioassay schematic diagram.

Representation of the IL-23 Bioassay. The IL-23 Bioassay consists of a genetically engineered cell line, IL-23 Bioassay Cells. When IL-23 binds to the IL-23 receptor (IL-23R), receptor-mediated pathway signaling induces luminescence that can be detected upon addition of Bio-Glo™ Reagent and quantified with a luminometer. Inhibition of IL-23 binding occurs by anti-IL-23 or anti-IL-23R antibody, resulting in a decrease in luminescence.

Assay Performance Data

Accuracy and precision are critical to bioassays and the development of biologics. This assay was developed and prequalified according to ICH guidelines for accuracy and precision, giving it the performance characteristics required for many applications of a bioassay used for antibody drug discovery research and development.

Accuracy: Measure of how close results are to a reference or "target" value.

IntraLab Precision: Measure of repeatability from multiple assays of the same homogeneous sample under the same operating conditions over a short time (same analyst; same lab; same day).

Intermediate Precision: Measure of repeatability of multiple assays of the same homogeneous sample with different analysts or equipment or on different days.

Linearity: Ability of the assay to provide measured values that are proportional to the concentration of the sample.

A 50–200% theoretical potency series of ustekinumab (anti-IL-23) was analyzed in triplicate in three independent experiments performed on three days by two analysts. Bio-Glo™ Reagent was added and luminescence quantified using the GloMax® Discover Detection System. Data were analyzed and relative potencies calculated after parallelism determination using JMP® software. Data were generated using thaw-and-use cells.
