4、成份时，用PBS（）稀释细胞悬液，细胞浓度达到100万/ml左右。通过反复冻融，以使细胞破坏并放出细胞内成份。离心20分钟左右（2000-3000转/分）。认真搜集上清。保留进程中如有沉淀形成，应再次离心。5. 组织标本：切割标本后，称取重量。加入必然量的PBS，。用液氮迅速冷冻保留备用。标本融化后仍然维持2-8的温度。加入必然量的PBS（），用手工或匀浆器将标本匀浆充分。离心20分钟左右（2000-3000转/分）。认真搜集上清。分装后一份待检测，其余冷冻备用。6. 标本搜集后及早进行提取，提取按相关文献进行，提取后应尽快进行实验。假设不能马上进行实验，可将标本放于-20保留，但应幸免反复冻

5、融.7. 不能检测含NaN3的样品，因NaN3抑制辣根过氧化物酶的（HRP）活性。操作步骤1.标准品的稀释与加样：在酶标包被板上设标准品孔10孔，在第一、第二孔中别离加标准品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别离加到第三孔和第四孔，再在第三、第四孔别离加标准品稀释液50l，混匀；然后在第三孔和第四孔中先各取50l弃掉，再各取50l别离加到第五、第六孔中，再在第五、第六孔中别离加标准品稀释液50ul，混匀；混匀后从第五、第六孔中各取50l别离加到第七、第八孔中，再在第七、第八孔中别离加标准品稀释液50l，混匀后从第七、第八孔中别离取50l

6、加到第九、第十孔中，再在第九第十孔别离加标准品稀释液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50l，浓度别离为120ng/L，60ng/L ，30ng/L，15ng/L，L）。2.加样：别离设空白孔（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，尽可能不触及孔壁，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：警惕揭掉封板

7、膜，弃去液体，甩干，每孔加满洗涤液，静置30秒后弃去，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，终止反映（现在蓝色立转黄色）。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分钟之内进行。注意事项：试剂盒从冷藏环境中掏出应在室温平稳15-30分钟后方可利用，酶标包被板开封后如未用完，板条应装入密封袋中保留。1浓洗涤液可能会有结晶析出，稀释时可在水浴中加温助溶

8、，洗涤时不阻碍结果。2各步加样均应利用加样器，并常常校对其准确性，以幸免实验误差。一次加样时刻最好操纵在5分钟内，如标本数量多，推荐利用排枪加样。3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太高（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必然倍数（n倍）后再测定，计算时请最后乘以总稀释倍数（n5）。4封板膜只限一次性利用，以幸免交叉污染。5底物请避光保留。6严格依照说明书的操作进行，实验结果判定必需以酶标仪读数为准.7所有样品，洗涤液和各类废弃物都应按传染物处置。8本试剂不同批号组分不得混用。10. 如与英文说明书有异，以英文说明书为准。计算：以标准物的浓度

9、为横坐标，OD值为纵坐标， 在坐标纸上绘出标准曲线，依照样品的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值为以上。2.批内与批见应别离小于9%和11%检测范围： 5ng/L -150ng/L 保留条件及有效期：1.试剂盒保留：；2-8。2有效期：6个月RDHuman Interleukin 1FOR RESEARCH USE ONLYDrug NamesGeneric Name：H
