1、高靈敏小鼠白細胞介素-6（IL-6）酶聯免疫分析（ELISA）試劑盒使用說明書金益柏試劑僅供研究使用 目的：本試劑盒用于測定小鼠血清，血漿樣本中白細胞介素-6（IL-6）含量。實驗原理： 本試劑盒應用雙抗體夾心法測定標本中小鼠白細胞介素6（IL-6）水平。用純化的小鼠白細胞介素6（IL-6）抗體包被微孔板，制成固相抗體，往包被單抗的微孔中依次加入白細胞介素6（IL-6），再與HRP標記的白細胞介素6（IL-6）抗體結合，形成抗體-抗原-酶標抗體復合物，經過徹底洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉化成藍色，并在酸的作用下轉化成最終的黃色。顏色的深淺和樣品中的白細胞介素6（IL-6）

2、呈正相關。用酶標儀在450nm波長下測定吸光度（OD值），通過標準曲線計算樣品中小鼠白細胞介素6（IL-6）濃度。試劑盒組成：試劑盒組成48孔配置96孔配置保存說明書1份1份封板膜2片（48）2片（96）密封袋1個1個酶標包被板1481962-8保存標準品：135pg/mL0.5ml1瓶0.5ml1瓶2-8保存標準品稀釋液1.5ml1瓶1.5ml1瓶2-8保存酶標試劑3 ml1瓶6 ml1瓶2-8保存樣品稀釋液3 ml1瓶6 ml1瓶2-8保存顯色劑A液3 ml1瓶6 ml1瓶2-8保存顯色劑B液3 ml1瓶6 ml1瓶2-8保存終止液3ml1瓶6ml1瓶2-8保存濃縮洗滌液（20ml20倍）

3、1瓶（20ml30倍）1瓶2-8保存樣本處理及要求：1.血清：室溫血液自然凝固10-20分鐘，離心20分鐘左右（2000-3000轉/分）。仔細收集上清，保存過程中如出現沉淀，應再次離心。2.血漿：應根據標本的要求選擇EDTA、者檸檬酸鈉或肝素作為抗凝劑，混合10-20分鐘后，離心20分鐘左右（2000-3000轉/分）。仔細收集上清，保存過程中如有沉淀形成，應該再次離心。3.尿液：用無菌管收集，離心20分鐘左右（2000-3000轉/分）。仔細收集上清，保存過程中如有沉淀形成，應再次離心。胸腹水、腦脊液參照實行。4.細胞培養上清：檢測分泌性的成份時，用無菌管收集。離心20分鐘左右（2000-

4、3000轉/分）。仔細收集上清。檢測細胞內的成份時，用PBS（PH7.2-7.4）稀釋細胞懸液，細胞濃度達到100萬/ml左右。通過反復凍融，以使細胞破壞并放出細胞內成份。離心20分鐘左右（2000-3000轉/分）。仔細收集上清。保存過程中如有沉淀形成，應再次離心。5.組織標本：切割標本后，稱取重量。加入一定量的PBS，PH7.4。用液氮迅速冷凍保存備用。標本融化后仍然保持2-8的溫度。加入一定量的PBS（PH7.4），用手工或勻漿器將標本勻漿充分。離心20分鐘左右（2000-3000轉/分）。仔細收集上清。分裝后一份待檢測，其余冷凍備用。6. 標本采集后盡早進行提取，提取按相關文獻進行，提

5、取后應盡快進行實驗。若不能馬上進行試驗，可將標本放于-20保存，但應避免反復凍融.7. 不能檢測含NaN3的樣品，因NaN3抑制辣根過氧化物酶的（HRP）活性。操作步驟1. 標準品的稀釋與加樣：在酶標包被板上設標準品孔10孔，在第一、第二孔中分別加標準品100l，然后在第一、第二孔中加標準品稀釋液50l，混勻；然后從第一孔、第二孔中各取100l分別加到第三孔和第四孔，再在第三、第四孔分別加標準品稀釋液50l，混勻；然后在第三孔和第四孔中先各取50l棄掉，再各取50l分別加到第五、第六孔中，再在第五、第六孔中分別加標準品稀釋液50ul，混勻；混勻后從第五、第六孔中各取50l分別加到第七、第八孔中

6、，再在第七、第八孔中分別加標準品稀釋液50l，混勻后從第七、第八孔中分別取50l加到第九、第十孔中，再在第九第十孔分別加標準品稀釋液50l，混勻后從第九第十孔中各取50l棄掉。（稀釋后各孔加樣量都為50l，濃度分別為90 pg/mL，60 pg/mL ，30 pg/mL，15 pg/mL，7.5 pg/mL）。2. 加樣：分別設空白孔（空白對照孔不加樣品及酶標試劑，其余各步操作相同）、待測樣品孔。在酶標包被板上待測樣品孔中先加樣品稀釋液40l，然后再加待測樣品10l（樣品最終稀釋度為5倍）。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。3. 溫育：用封板膜封板后置37溫育30分鐘。

7、4. 配液：將30（48T的20倍）倍濃縮洗滌液用蒸餾水30（48T的20倍）倍稀釋后備用。5. 洗滌：小心揭掉封板膜，棄去液體，甩干，每孔加滿洗滌液，靜置30秒后棄去，如此重復5次，拍干。6. 加酶：每孔加入酶標試劑50l，空白孔除外。7. 溫育：操作同3。8. 洗滌：操作同5。9. 顯色：每孔先加入顯色劑A50l，再加入顯色劑B50l，輕輕震蕩混勻，37避光顯色15分鐘. 10. 終止：每孔加終止液50l，終止反應（此時藍色立轉黃色）。11. 測定：以空白空調零，450nm波長依序測量各孔的吸光度（OD值）。 測定應在加終止液后15分鐘以內進行。注意事項：1 試劑盒從冷藏環境中取出應在室溫

8、平衡15-30分鐘后方可使用，酶標包被板開封后如未用完，板條應裝入密封袋中保存。2 濃洗滌液可能會有結晶析出，稀釋時可在水浴中加溫助溶，洗滌時不影響結果。3 各步加樣均應使用加樣器，并經常校對其準確性，以避免試驗誤差。一次加樣時間最好控制在5分鐘內，如標本數量多，推薦使用排槍加樣。4 請每次測定的同時做標準曲線，最好做復孔。如標本中待測物質含量過高（樣本OD值大于標準品孔第一孔的OD值），請先用樣品稀釋液稀釋一定倍數（n倍）后再測定，計算時請最后乘以總稀釋倍數（n5）。5 封板膜只限一次性使用，以避免交叉污染。6 底物請避光保存。7 嚴格按照說明書的操作進行，試驗結果判定必須以酶標儀讀數為準.

9、8 所有樣品，洗滌液和各種廢棄物都應按傳染物處理。9 本試劑不同批號組分不得混用。10. 如與英文說明書有異，以英文說明書為準。計算：以標準物的濃度為橫坐標，OD值為縱坐標， 在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。 試劑盒性能：1.樣品線性回歸與預期濃度相關系數R值為0.95以上。2.批內與批間應分別小于9%和11%檢測范圍： 5 pg/mL -100 pg/mL 保存條件及有效期：1.試劑盒保存：；2-8。
