小鼠肝脂酶(HL)ELISA試劑盒僅供課題研究使用
自備材料:
1. 蒸餾水。
2. 加樣器:5ul、10ul、50ul、100ul、200ul、500ul、1000ul。
3. 振蕩器及磁力攪拌器等。
樣品收集、處理及保存方法:
1、 血清……操作過程中避免任何細胞刺激。使用不含熱原和內毒素的試管。收集血液后,1000×g離心10分鐘將血紅細胞迅速小心地分離。
2、 血漿……EDTA、檸檬酸鹽、肝素血漿可用于檢測。1000×g離心30分鐘去除顆粒。
3、 細胞上清液……1000×g離心10分鐘去除顆粒和聚合物。
4、 組織勻漿……將組織加入適量理鹽水搗碎。1000×g離心10分鐘,取上清液。
5、 保存……如果樣品不立即使用,應將其分成小部分-70℃保存,避免反復冷凍。盡可能的不要使用溶血或高血脂血。如果血清中大量顆粒,檢測前先離心或過濾。不要在37℃或更高的溫度加熱解凍。應在室溫下解凍并確保樣品均勻地充分解凍。
操作注意事項:
● 試劑應按標簽說明書儲存,使用前恢復到室溫。稀稀過后的標準品應丟棄,不可保存。
● 實驗中不用的板條應立即放回包裝袋中,密封保存,以免變質。
● 不用的其它試劑應包裝好或蓋好。不同批號的試劑不要混用。保質前使用。
● 使用一次性的吸頭以免交叉污染,吸取終止液和底物A、B液時,避免使用帶金屬部分的加樣器。
● 使用干凈的塑料容器配置洗滌液。使用前充分混勻試劑盒里的各種成份及樣品。
● 底物A應揮發,避免長時間打開蓋子。底物B對光敏感,避免長時間暴露于光下。避免用手接觸,有毒。實驗完成后應立即讀取OD值。
● 加入試劑的順序應*,以保證所有反應板孔溫育的時間一樣。
● 按照說明書中標明的時間、加液的量及順序進行溫育操作。
操作步驟:
1. 使用前,將所有試劑充分混勻。不要使液體產生大量的泡沫,以免加樣時加入大量的氣泡,產生加樣上的誤差。
2. 根據待測樣品數量加上標準品的數量決定所需的板條數。每個標準品和空白孔建議做復孔。每個樣品根據自己的數量來定,能使用復孔的盡量做復孔。
3. 加入稀釋好后的標準品50ul于反應孔、加入待測樣品50ul于反應孔內。立即加入50ul的生物素標記的抗體。蓋上膜板,輕輕振蕩混勻,37℃溫育45分鐘。
4. 甩去孔內液體,每孔加滿洗滌液,振蕩30秒,甩去洗滌液,用吸水紙拍干。重復此操作4次。如果用洗板機洗滌,洗滌次數增加一次。
5. 每孔加入100ul的親和鏈酶素-HRP,輕輕振蕩混勻,37℃溫育30分鐘。
6. 甩去孔內液體,每孔加滿洗滌液,振蕩30秒,甩去洗滌液,用吸水紙拍干。重復此操作4次。如果用洗板機洗滌,洗滌次數增加一次。
7. 每孔加入底物A、B各50ul,輕輕振蕩混勻,37℃溫育5分鐘。避免光照。
8. 取出酶標板,迅速加入50ul終止液,加入終止液后應立即測定結果。
9. 在450nm波長處測定各孔的OD值。
