Selective and Sensitive Detection of Monoamine Oxidase Activity

MAO-Glo™ Assay Systemは、モノアミン-オキシダーゼ(MAO)活性を発光法により検出するホモジニアスタイプの定量システムです。リコンビナントまたはネイティブなMAO酵素の活性に対するテスト化合物の影響を調べるために使用します。MAO-Glo™ AssayはMAO酵素と発光前駆体MAO基質とのインキュベーションにより行われます。MAO-Glo™ Assayの基質は甲虫ルシフェリンの類似体で、MAOによりルシフェリンに変換され、発光を生じるルシフェラーゼ反応に供されます。生じた発光量はMAO活性に比例します。
MAO反応が完了後、Luciferin Detection Reagentを添加します。この試薬はMAO反応を停止させるとともに5時間以上の発光半減期を持つ安定なグロータイプの発光シグナルを開始させます。この長時間発光により測光時間の厳密な管理が不要になります。
MAO-Glo™ Assayは発光前駆体MAO基質と2種類のMAO反応バッファー(1つはMAO AおよびMAO B用、もう1つはMAO B専用)、凍結乾燥されたLuciferin Detection ReagentおよびLuciferin Detection Bufferから構成されます。準備するものはMAOを含むサンプルだけです。プロトコルはマルチウェルプレート形式で設定されていますが、シングル-チューブにも簡単に適応できます。
  • 完全なソリューション:MAO-Glo™ Assay with MAO-AにはモノアミンオキシダーゼA酵素が含まれるのでMAO-A活性に対する化合物の影響も簡便に評価可能
  • スピード:発光法はHPLCなどの方法よりも短時間で測定可能
  • 簡便:シンプルな添加-測定だけのプロトコルはマルチ ウェルプレートを用いたハイスループットスクリーニングを可能にします
  • 高感度:標準的なHPLC法や蛍光法に比べ少量のMAO酵素で測定可能
  • 正確:発光法はテスト化合物由来の蛍光に影響を受けません
  • 安定な発光:発光の半減期は5時間以上

  • 様々な細胞株におけるネイティブなMAO活性の測定
  • リコンビナントMAO活性の測定
  • ネイティブ/リコンビナント画分のMAO活性を変化させる薬剤/化合物のスクリーニング

Conversion of the MAO Substrate by MAO. Monoamine oxidase acts on the luminogenic MAO Substrate to produce methyl ester luciferin, which is then converted into light by the esterase and luciferase enzymes in the reconstituted Luciferin Detection Reagent. Any effects of test compounds on luciferase or esterase activities have been minimized.

MAO-Glo is >100x more sensitive than fluorometric methods. MAO-Glo provides expanded dynamic range and a more sensitive assay compared to fluorescent assay alternatives.

Measure Monoamine Oxidase Inhibitor Activity with MAO-Glo

MAO-A (Panel A) and MAO-B (Panel B) reactions were performed in the presence of various inhibitors and the luminescent signal was measured. Results correlate with known activity of inhibitors.

Screening for MAO Inhibitors and Substrates

Monoamine oxidases process neurotransmitters (norepinephrine, serotonin, dopamine) in the brain. MAO-A and MAO-B are found in neurons and astroglia, while MAO-A is also active in the liver and other tissues. MAO dysfunction is thought to be responsible for several psychiatric and neurological disorders. An emerging research area for MAO enzymes surrounds their role in degradation of certain psychedelic treatments. MAOI (monoamine oxidase inhibitors) are a key class of antidepressant treatments and are being studied for neurodegenerative disease treatment.

Screening for monoamine oxidase inhibitors or substrates with the luminescent MAO-Glo™ Assay System decreases the false-hit rate compared to fluorescent assays, which have a false-hit rate as high as 10%. See the data in the article The MAO-Glo™ Assay: A Bioluminescent, Coupled Assay for Monoamine Oxidase Activity.
