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

IL-6は、IL-11、白血病抑制因子(LIF)、オンコスタチンM、毛様体神経栄養因子(CNTF)、カルジオトロフィン-1(CT-1)、およびカルジオトロフィン様サイトカイン(CLC)を含むIL-6サイトカインファミリーのメンバーです。 これらのサイトカインはすべて、gp130およびSTAT3経路を介してシグナルを伝達します。IL-6は、UV照射、活性酸素種、微生物やウイルスなどの組織損傷またはストレス要因に続いて一時的に分泌されます。また、細菌性敗血症中に放出されるサイトカインの1つです。さらに、IL-6は、トランスフォーミング増殖因子β(TGFβ)とともに、CD4 + T細胞のTh17細胞への分化を促進し、制御性T細胞の分化を阻害するため、自己免疫に重要な役割を果たします。 

IL-6バイオアッセイは、IL-6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-6バイオアッセイ細胞は、IL-6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-6がIL-6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

The IL-6 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.# JA2501, JA2505).

IL-6 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.# J2992).

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-6 Bioassay schematic diagram.

Representation of the IL-6 Bioassay. The IL-6 Bioassay consists of a genetically engineered cell line, IL-6 Bioassay Cells. When IL-6 binds to the IL-6 receptor (IL-6R), receptor-mediated pathway signaling induces luminescence that can be detected upon addition of Bio-Glo™ Reagent, and quantified with a luminometer. Inhibition of IL-6 binding by anti-IL-6 or anti-IL-6R 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.

A 50–150% theoretical potency series of tocilizumab (anti-IL-6R) 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.

IL-6 Bioassay Cells were grown and prepared as described in the protocol, and incubated with serial dilutions of recombinant IL-6. After a 4-, 5-, 6- or 24-hour incubation, Bio-Glo™ Reagent was added, and luminescence was quantified using the GloMax® Discover System.

Tocilizumab (anti-IL-6R) was treated with various concentrations of hydrogen peroxide (0–0.05%) for 18 hours at 26°C prior to use in the IL-6 Bioassay. Bio-Glo™ Reagent was added, and luminescence was quantified using the GloMax® Discover System.
