安定した結果が得られるシンプルな IL-2 バイオアッセイ

1976年に T-細胞成長因子として発見されたインターロイキン-2  (IL-2) は、CD4+および CD8+ T 細胞、ナチュラルキラー (NK) 細胞、活性化樹状細胞など様々な細胞種により分泌される単量体タンパク質(15.5kDa)です。 IL-2 は免疫システムに多面的に影響を与えています。また、 CD4+ 制御性 T 細胞の生成、維持、展開に重要な役割を果たしており、CD8+ NK 細胞の細胞毒性活性を促進し、活性化誘導型細胞死 を介して有害な自己反応性T細胞を除去して恒常性を維持しています。

IL-2 Bioassay は  STAT-5 応答配列を利用して IL-2 による刺激や阻害を測定するためにデザインされた細胞ベース発光アッセイです。IL-2 Bioassay には "thaw-and-use" の簡単フォーマットで使用できる凍結保存細胞が含まれており、細胞を融解した後、細胞を増やすことなくそのままアッセイに使用することができます。 IL-2 Bioassay には  融解して、増殖、バンキングが許容された凍結保存細胞を含む長期使用のための Cell Propagation Model (CPM) フォーマットもご利用いただけます (IL-2 Bioassay, Propagation Model, カタログ番号 J2952)。

アッセイの構成品

The IL-2 Bioassay Cells included 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.# JA2201, JA2205).

The IL-2 Bioassay is also available in a Cell Propagation Model (CPM) format, as cryopreserved cells, that can be thawed, propagated and banked for long-term use (Cat.# J2952).

アッセイの原理

 
How the IL-2 Bioassay works. 15414ma

Representation of the IL-2 Bioassay. The IL-2 Bioassay consists of a genetically engineered cell line, IL-2 Bioassay Cells. When IL-2 binds to its receptor, receptor-mediated pathway signaling induces luminescence that can be detected upon addition of Bio-Glo™ Reagent and quantified with a luminometer. In the absence of IL-2, no signaling occurs downstream of IL-2R and no luminescent signal is generated.

アッセイパフォーマンスデータ

正確度 (accuracy) と 精度 (precision) はバイオアッセイやバイオロジックス開発において非常に重要です。IL-2 Bioassay は正確度と 精度を兼ね備えたアッセイです(正確度とは標的または参照値に対してどれほど近かったかという度合いであり、精度は再現性の度合いです)。本アッセイは正確度 と 精度 のためのICHガイドラインに従い開発、事前承認されており、抗体医薬の研究開発に使用するバイオアッセイの様々なアプリケーションに必要とされるパフォーマンス特性を備えています。

A 50–200% theoretical potency series of aldesleukin (therapeutic IL-2) 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 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.
