首先通過文獻檢索的方式了解待測樣本的大致含量,確定適當的稀釋倍數。只有稀釋至標準曲線的范圍內,檢測的結果才是準確的。稀釋的過程中,應做好詳細的記錄。zui后計算濃度時,稀釋了“N”倍,標本的濃度應再乘以“N”。
標準品的稀釋原則:2瓶,每瓶臨用前以樣品稀釋液稀釋至1ml,蓋好后靜置10分鐘以上,然后反復顛倒/搓動以助溶解,其濃度為300 pg/ml,做系列倍比稀釋后,分別稀釋300 pg/ml,150 pg/ml,75 pg/ml,37.5 pg/ml,18.5 pg/ml,9 pg/ml,4.5 pg/ml,樣品稀釋液直接作為標準濃度0 pg/ml,臨用前15分鐘內配制。
如配制150 pg/ml標準品:取0.5ml(不要少于0.5ml)300 pg/ml的上述標準品加入含0.5ml樣品稀釋液的Eppendorf管中,混勻即可,其余濃度以此類推。
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。
