人抗酒石酸酸性磷酸酶5b(TRACP5b)酶聯(lián)免疫分析(ELISA) 試劑盒使用

1、人抗酒石酸酸性磷酸酶5b(TRACP5b)酶聯(lián)免疫分析（ELISA）試劑盒使用說明書本試劑僅供研究使用 目的：本試劑盒用于測定人血清，血漿及相關液體樣本中抗酒石酸酸性磷酸酶5b(TRACP5b)的含量。實驗原理： 本試劑盒應用雙抗原夾心法測定標本中人抗酒石酸酸性磷酸酶5b(TRACP5b)水平。用純化的 TRACP5b抗原包被微孔板，制成固相抗原，往包被抗原的微孔中依次加入抗酒石酸酸性磷酸酶5b(TRACP5b)，再與HRP標記的酒石酸酸性磷酸酶5b抗原結合，形成抗原-抗體-酶標抗原復合物，經(jīng)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

2、的深淺和樣品中的抗酒石酸酸性磷酸酶5b(TRACP5b)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人抗酒石酸酸性磷酸酶5b(TRACP5b)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1×481×962-8保存標準品：3600 pg/L0.5ml×1瓶0.5ml×1瓶2-8保存標準品稀釋液1.5ml×1瓶1.5ml×1瓶2-8保存酶標試劑3 ml×1瓶6 ml×1瓶2-8保存樣品稀釋液3 ml×

6、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，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2400pg/ L，1600pg/ L ，800pg/ L，400pg

7、/ L， 200pg/ L）。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。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。

8、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(diào)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(nèi)進行。注意事項：1 試劑盒從冷藏環(huán)境中取出應在室溫平衡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(jīng)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(nèi)，如標本數(shù)量多，推薦使用排槍加樣。

9、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(shù)（n倍）后再測定，計算時請最后乘以總稀釋倍數(shù)（×n×5）。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(shù)為準.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(jù)樣品的OD 值由標準曲線查出相應的濃度；再乘以稀釋 倍

10、數(shù)；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(shù)，即為樣品的實際濃度。 （此圖僅供參考）試劑盒性能：1.樣品線性回歸與預期濃度相關系數(shù)R值為0.92以上。2.批內(nèi)與批見應分別小于9%和15%檢測范圍： 100pg/ L-3000pg/ L 保存條件及有效期：1.試劑盒保存：；2-8。2有效期：6個月 Human tartrate-resistant acid phosphatase 5bFOR RESEARCH USE ONLYDrug NamesGeneric Name：Human tartrate-resistant
