操作步驟
實驗開始前,請提前配置好所有試劑,試劑或樣品稀釋時,均需混勻,混勻時盡量避免起泡。每次檢測都應該做標準曲線。如樣品濃度過高時,用樣品稀釋液進行稀釋,以使樣品符合試劑盒的檢測范圍。
1. 加樣:分別設空白孔、標準孔、待測樣品孔。空白孔加樣品稀釋液100μl,余孔分別加標準品或待測樣品100μl,注意不要有氣泡,加樣將樣品加于酶標板孔底部,盡量不觸及孔壁,輕輕晃動混勻,酶標板加上蓋或覆膜,37℃反應120分鐘。
為保證實驗結果有效性,每次實驗請使用新的標準品溶液。
2. 棄去液體,甩干,不用洗滌。每孔加生物素標記抗體工作液 100μl(取1μl生物素標記抗體加99μl生物素標記抗體稀釋液的比例配制,輕輕混勻,在使用前一小時內配制),37℃,60分鐘。
3. 溫育60分鐘后,棄去孔內液體,甩干,洗板3次,每次浸泡1-2分鐘,350μl/每孔,甩干。
4. 每孔加辣根過氧化物酶標記親和素工作液(同生物素標記抗體工作液) 100μl,37℃,60分鐘。
5. 溫育60分鐘后,棄去孔內液體,甩干,洗板5次,每次浸泡1-2分鐘,350μl/每孔,甩干。
6. 依序每孔加底物溶液90μl,37℃避光顯色(30分鐘內,此時肉眼可見標準品的前3-4孔有明顯的梯度藍色,后3-4孔梯度不明顯,即可終止)。
7. 依序每孔加終止溶液50μl,終止反應(此時藍色立轉黃色)。終止液的加入順序應盡量與底物液的加入順序相同。為了保證實驗結果的準確性,底物反應時間到后應盡快加入終止液。
8. 用酶聯儀在450nm波長依序測量各孔的光密度(OD值)。 在加終止液后15分鐘以內進行檢測。
注:
1. 用戶在初次使用試劑盒時,應將各種試劑管離心數分鐘,以便試劑集中到管底。
2. 每次實驗留一孔作為空白調零孔,該孔不加任何試劑,只是zui后加底物溶液及2N H2SO4。測量時先用此孔調OD值至零。
3. 為防止樣品蒸發,試驗時將反應板放于鋪有濕布的密閉盒內,酶標板加上蓋或覆膜。
4. 未使用完的酶標板或者試劑,請于2-8℃保存。標準品、生物素標記抗體工作液、辣根過氧化物酶標記親和素工作液請依據所需的量配置使用。請勿重復使用已稀釋過的標準品、生物素標記抗體工作液或、辣根過氧化物酶標記親和素工作液。
5. 建議檢測樣品時均設雙孔測定,以保證檢測結果的準確性。
洗板方法
手工洗板方法:吸去(不可觸及板壁)或甩掉酶標板內的液體;在實驗臺上鋪墊幾層吸水紙,酶標板朝下用力拍幾次;將*的洗滌緩沖液至少0.3ml注入孔內,浸泡1-2分鐘。根據需要,重復此過程數次。
自動洗板:如果有自動洗板機,應在熟練使用后再用到正式實驗過程中。
計算
以標準物的濃度為橫坐標(對數坐標),OD值為縱坐標(普通坐標),在半對數坐標紙上繪出標準曲線,根據樣品的OD值由標準曲線查出相應的濃度;再乘以稀釋倍數;或用標準物的濃度與OD值計算出標準曲線的直線回歸方程式,將樣品的OD值代入方程式,計算出樣品濃度,再乘以稀釋倍數,即為樣品的實際濃度。
小鼠α1酸性糖蛋白(α1-AGP)ELISA試劑盒注意事項
1. 當混合蛋白溶液時應盡量輕緩,避免起泡。
2. 洗滌過程非常重要,不充分的洗滌易造成假陽性。
3. 一次加樣時間控制在5分鐘內,如標本數量多,*使用排槍加樣。
4. 請每次測定的同時做標準曲線,做復孔。
5. 如標本中待測物質含量過高,請先稀釋后再測定,計算時請zui后乘以稀釋倍數。
6. 在配制標準品、檢測溶液工作液時,請以相應的稀釋液配制,不能混淆。
7. 底物請避光保存。
8. 不要用其它生產廠家的試劑替換試劑盒中的試劑。
