人乙型腦炎病毒IgM抗體（JEV-IgM）ELISA檢測試劑盒.
檢測原理
試劑盒采用間接法酶聯免疫吸附試驗（elisa）。往預先包被人乙型腦炎病毒igm抗體（jev-igm）捕獲抗原的包被微孔中，依次加入標本、標準品、hrp標記的檢測抗體，經過溫育并*洗滌。用底物tmb顯色，tmb在過氧化物酶的催化下轉化成藍色，并在酸的作用下轉化成終的黃色。顏色的深淺和樣品中的人乙型腦炎病毒igm抗體（jev-igm）呈正相關。用酶標儀在450nm 波長下測定吸光度（od 值），判斷樣品是否含有人乙型腦炎病毒igm抗體（jev-igm）。
樣品收集、處理及保存方法
1. 血清：使用不含熱原和內毒素的試管，操作過程中避免任何細胞刺激，收集血液后，3000轉離心10分鐘將血清和紅細胞迅速小心地分離。
2. 血漿：edta、檸檬酸鹽或肝素抗凝。3000轉離心30分鐘取上清。
3. 細胞上清液：3000轉離心10分鐘去除顆粒和聚合物。
4. 組織勻漿：將組織加入適量生理鹽水搗碎。3000轉離心10分鐘取上清。
5. 保存：如果樣本收集后不及時檢測，請按一次用量分裝，凍存于-20℃，避免反復凍融，在室溫下解凍并確保樣品均勻地充分解凍。
自備物品
酶標儀（450nm）高精度加樣器及槍頭：0.5-10ul、2-20ul、20-200ul、200-1000ul37℃恒溫箱操作注意事項
試劑盒保存在2-8℃，使用前室溫平衡20分鐘。從冰箱取出的濃縮洗滌液會有結晶，這屬于正常現象，水浴加熱使結晶*溶解后再使用。實驗中不用的板條應立即放回自封袋中，密封（低溫干燥）保存。預處理后的樣本無需稀釋，直接取10μl加樣即可。嚴格按照說明書中標明的時間、加液量及順序進行溫育操作。所有液體組分使用前充分搖勻。試劑盒組成

試劑的準備
20×洗滌緩沖液的稀釋：蒸餾水按1：20稀釋，即1份的20×洗滌緩沖液加19份的蒸餾水。
洗板方法
手工洗板：甩盡孔內液體，每孔加滿洗滌液，靜置1min后甩盡孔內液體，在吸水紙上拍干，如此洗板5次。自動洗板機：每孔注入洗液350μl，浸泡1min，洗板5次。操作步驟
從室溫平衡20min后的鋁箔袋中取出所需板條，剩余板條用自封袋密封放回4℃。設置陰、陽性對照孔和樣本孔，陰、陽性對照孔中加入陰性對照、陽性對照各50μl；待測樣本孔先加待測樣本10μl，再加*40μl；隨后陰、陽性對照孔和樣本孔中每孔加入辣根過氧化物酶（hrp）標記的檢測抗體100μl，用封板膜封住反應孔，37℃水浴鍋或恒溫箱溫育60min。棄去液體，吸水紙上拍干，每孔加滿洗滌液，靜置1min，甩去洗滌液，吸水紙上拍干，如此重復洗板5次（也可用洗板機洗板）。每孔加入底物a、b各50μl，37℃避光孵育15min。每孔加入終止液50μl，15min內，在450nm波長處測定各孔的od值。結果判斷
1. 試驗有效性：陽性對照孔od值平均值≥1.00；
陰性對照孔od值平均值≤0.15。
2. 臨界值（cut off）計算：臨界值=陰性對照孔平均值+0.15
3. 陰性判斷：樣品od值＜臨界值（cut off），樣品為陰性
4. 陽性判斷：樣品od值＞臨界值（cut off），樣品為陽性
試劑盒性能
準確性：陽性對照孔od值平均值≥1.00；陰性對照孔od值平均值≤0.15，說明試驗結果有效。特異性：不與其它可溶性結構類似物交叉反應。重復性：板內、板間變異系數均小于15%。貯藏：2-8℃，避光防潮保存。有效期：6個月免責聲明
試劑盒僅供研究使用，不得用于臨床實驗或人體實驗，否則所產生的一切后果，由實驗者承擔，本公司概不負責。嚴格按照說明書操作，實驗者違反說明書操作，后果由實驗者承擔。
