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-12（IL-12）は、IL-12、IL-23、IL-27、IL-35およびIL-39を含む IL-12サイトカインファミリーのメンバーです。IL-12 と IL-23は両方とも複合サイトカインであり、共通の IL-12 p40サブユニットとIL-12Rβ1受容体を共有しています。サイトカイン特異性は、IL-12Rβ2に結合するユニークなIL-12 p35サブユニットとIL-23Rに結合するIL-23p19サブユニットに由来します。アクティブなヘテロダイマーとそれに続くIL-12シグナルを生成するには、p35 と p40 の両方の遺伝子を同じ細胞内で発現させる必要があります。IL-12 は、バクテリアや他の微生物による食細胞および樹状細胞の刺激後に分泌されます。
IL-12 Bioassay は、IL-12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-12バイオアッセイ細胞は、IL-12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-12がIL-12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て発光します。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
The IL-12 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.# JA2601, JA2605).
IL-12 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.# J3042).
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
Representation of the IL-12 Bioassay. The IL-12 Bioassay consists of a genetically engineered cell line, IL-12 Bioassay Cells. When IL-12 binds to the IL-12 receptor (IL-12R), receptor-mediated pathway signaling induces luminescence that can be detected upon addition of Bio-Glo™ Reagent and quantified with a luminometer. Inhibition of IL-12 binding by anti-IL-12 or anti-IL-12R antibodies results 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.
The IL-12 Bioassay Shows Precision, Accuracy and Linearity.

| A 50–200% theoretical potency series of ustekinumab (anti-IL-12) 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. | ||
The IL-12 Bioassay responds to recombinant IL-12.
IL-12 Bioassay Cells were prepared as described in the protocol and incubated with serial dilutions of recombinant IL-12. After a 4-, 5-, 6- or 24-hour incubation, Bio-Glo™ Reagent was added, and luminescence was quantified using the GloMax® Discover System.
The IL-12 Bioassay indicates stability.
Ustekinumab was heat treated at 65°C for 0–6 hours prior to use in the IL-12 Bioassay. Bio-Glo™ Reagent was added, and luminescence was quantified using the GloMax® Discover System.
