4、第二孔中分别加标准品 100l，然后在第一、第二孔中加标准品稀释液 50l，混匀；然后从第一孔、第二孔中各取 100l 分别加到第三孔和第四孔，再在第三、第四孔分别加标准品稀释液250l，混匀；然后在第三孔和第四孔中先各取 50l 弃掉，再各取 50l 分别加到第五、第六孔中，再在第五、第六孔中分别加标准品稀释液 50ul，混匀；混匀后从第五、第六孔中各取 50l 分别加到第七、第八孔中，再在第七、第八孔中分别加标准品稀释液50l，混匀后从第七、第八孔中分别取 50l 加到第九、第十孔中，再在第九第十孔分别加标准品稀释液 50l，混匀后从第九第十孔中各取 50l 弃掉。 （稀释后各孔加样量都为
5、 50l，浓度分别为 150ng/L，100ng/L ，50ng/L，25ng/L，12.5ng/L） 。2. 加样：分别设空白孔（空白对照孔不加样品及酶标试剂，其余各步操作相同） 、待测样品孔。在酶标包被板上待测样品孔中先加样品稀释液 40l，然后再加待测样品10l（样品最终稀释度为 5 倍） 。加样将样品加于酶标板孔底部，尽量不触及孔壁，轻轻晃动混匀。3. 温育：用封板膜封板后置 37温育 30 分钟。4. 配液：将 30（48T 的 20 倍）倍浓缩洗涤液用蒸馏水 30（48T 的 20 倍）倍稀释后备用。5. 洗涤：小心揭掉封板膜，弃去液体，甩干，每孔加满洗涤液，静置 30 秒后弃去，
6、如此重复 5 次，拍干。6. 加酶：每孔加入酶标试剂 50l，空白孔除外。7. 温育：操作同 3。8. 洗涤：操作同 5。9. 显色：每孔先加入显色剂 A50l，再加入显色剂 B50l，轻轻震荡混匀，37避光显色15 分钟. 10. 终止：每孔加终止液 50l，终止反应（此时蓝色立转黄色） 。11. 测定：以空白空调零，450nm 波长依序测量各孔的吸光度（OD 值） 。 测定应在加终止液后 15 分钟以内进行。注意事项：1 试剂盒从冷藏环境中取出应在室温平衡 15-30 分钟后方可使用，酶标包被板开封后如未用完，板条应装入密封袋中保存。2 浓洗涤液可能会有结晶析出，稀释时可在水浴中加温助溶，
7、洗涤时不影响结果。3 各步加样均应使用加样器，并经常校对其准确性，以避免试验误差。一次加样时间最好控制在 5 分钟内，如标本数量多，推荐使用排枪加样。4 请每次测定的同时做标准曲线，最好做复孔。如标本中待测物质含量过高（样本 OD值大于标准品孔第一孔的 OD 值） ，请先用样品稀释液稀释一定倍数（ n 倍）后再测定，计算时请最后乘以总稀释倍数（n5） 。5 封板膜只限一次性使用，以避免交叉污染。6 底物请避光保存。7 严格按照说明书的操作进行，试验结果判定必须以酶标仪读数为准.8 所有样品，洗涤液和各种废弃物都应按传染物处理。9 本试剂不同批号组分不得混用。10. 如与英文说明书有异，以英文说
8、明书为准。3计算：以标准物的浓度为横坐标，OD 值为纵坐标， 在坐标纸上绘出标准曲线，根据样品的 OD 值由标准曲线查出相应的浓度；再乘以稀释 倍数；或用标准物的浓度与 OD 值计算出标 准曲线的直线回归方程式，将样品的 OD 值 代入方程式，计算出样品浓度，再乘以稀释 倍数，即为样品的实际浓度。 （此图仅供参考）试剂盒性能：1.样品线性回归与预期浓度相关系数 R 值为 0.95 以上。2.批内与批见应分别小于 9%和 11%检测范围： 6ng/L -200ng/L 保存条件及有效期：1.试剂盒保存：；2-8。2有效期：6 个月412-oxo-phytodienoic acid reducta
