簡便な RANKL バイオアッセイ, 安定した結果

NFκB活性化受容体 (RANK/TRANCE receptor/TNFRSF11A) は 腫瘍壊死因子受容体 (TNFR) ファミリーのメンバーです。 この受容体に対するリガンドであるRANKL の結合 は骨代謝回転率の増加により特長付けられるいくつかの病態や骨のモデリングおよびリモデリングにおける破骨細胞の形成、活性化および生存を調節します。

RANKL Bioassay は RANKLの刺激または阻害を測定するためにデザインされた発光セルベースアッセイです。RANKL Bioassay に含まれる細胞は RANKLシグナル に応答して luc2P を発現するために改変されています。RANKL が結合すると、受容体は細胞内にシグナルを伝達し、結果的に発光を生じます。この生物発光シグナルは Bio-Glo™ Reagent を用いて検出、定量されます。

Assay Components

RANKL 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.# JA2701, JA2705).

RANKL 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.# J3102).

Workflow

Standard bioassay workflow with cultured cells
Improved bioassay workflow with thaw-and-use cells

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

Schematic of the RANKL Bioassay. 16461ma-01

Representation of the RANKL Bioassay. The RANKL Bioassay consists of a genetically engineered cell line, RANKL Bioassay Cells. When RANKL binds to its receptor, receptor-mediated pathway signaling induces luminescence that can be detected upon the addition of Bio-Glo™ Reagent and quantified with a luminometer. Inhibition of RANKL binding by anti-RANKL antibody 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 denosumab (anti-RANKL) was analyzed in triplicate in three independent experiments performed on three days by two analysts (for a total of six independent experiments). Bio-Glo™ Reagent was added, and luminescence was quantified using the GloMax® Discover System. Data were analyzed and relative potencies calculated after parallelism determination using JMP® software. Data were generated using thaw-and-use cells.

The RANKL Bioassay responds to recombinant RANKL. RANKL Bioassay Cells were grown and prepared as described in this protocol, and incubated with serial dilutions of recombinant RANKL. After a 6-hour incubation, Bio-Glo™ Reagent was added, and luminescence was quantified using the GloMax® Discover System. This graph shows raw luminescence measurements.
