人棘球蚴IgM抗体酶联免疫分析（ELISA）
试剂盒使用说明书
本试剂仅供研究使用 目的：本试剂盒用于测定人血清，血浆及相关液体样本中棘球蚴IgM抗体的含量。
实验原理：
本试剂盒应用双抗原夹心法测定标本中人棘球蚴IgM抗体水平。用纯化的人棘球蚴IgM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棘球蚴IgM抗体，再与HRP标记的棘球蚴IgM抗原结合，形成抗原-抗体-酶标抗原复合物，经过洗涤后加底物TMB显色。TMB在HRP酶的催化下转化成蓝色，并在酸的作用下转化成最终的黄色。颜色的深浅和样品中的棘球蚴IgM抗体呈正相关。用酶标仪在450nm波长下测定吸光度（OD值），通过标准曲线计算样品中人棘球蚴IgM抗体浓度。

（20ml×20倍）×1瓶 |
样本处理及要求：
1.血清：室温血液自然凝固10-20分钟，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如出现沉淀，应再次离心。
2.血浆：应根据标本的要求选择EDTA或柠檬酸钠作为抗凝剂，混合10-20分钟后，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应该再次离心。
3.尿液：用无菌管收集，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应再次离心。胸腹水、脑脊液参照实行。
4.细胞培养上清：检测分泌性的成份时，用无菌管收集。离心20分钟左右（2000-3000转/分）。仔细收集上清。检测细胞内的成份时，用PBS（PH7.2⁻⁷.4）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）。仔细收集上清。保存过程中如有沉淀形成，应再次离心。
5.组织标本：切割标本后，称取重量。加入一定量的PBS，PH7.4。用液氮迅速冷冻保存备用。标本融化后仍然保持2-8℃的温度。加入一定量的PBS（PH7.4），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）。仔细收集上清。分装后一份待检测，其余冷冻备用。
6.标本采集后尽早进行提取，提取按相关文献进行，提取后应尽快进行实验。若不能马上进行试验，可将标本放于-20℃保存，但应避免反复冻融.
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、第二孔中分别加标准品100μl，然后在、第二孔中加标准品稀释液50μl，混匀；然后从孔、第二孔中各取100μl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50μl，混匀；然后在第三孔和第四孔中先各取50μl弃掉，再各取50μl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50μl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50μl，混匀后从第七、第八孔中分别取50μl加到第九、第十孔中，再在第九第十孔分别加标准品稀释液50μl，混匀后从第九第十孔中各取50μl弃掉。（稀释后各孔加样量都为50μl，浓度分别为90pg/ml，60pg/ml，30pg/ml，15pg/ml，7.5pg/ml。
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40μl，然后再加待测样品10μl（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，如此重复5次，拍干。
6. 加酶：每孔加入酶标试剂50μl，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A50μl，再加入显色剂B50μl，轻轻震荡混匀，37℃避光显色15分钟.
10. 终止：每孔加终止液50μl，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，洗涤时不影响结果。
3． 各步加样均应使用加样器，并经常校对其性，以避免试验误差。一次加样时间控制在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，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，计算时请乘以总稀释倍数（×n×5）。
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，以英文说明书为准。

11.assay：take blank well as zero ,Read absorbance at 450nmafterAddingStop Solution ａnd within 15min.
Important notes
1. The kit takes out from the refrigeration environment should be balanced 15-30 minutes in the room temperature,ELISA plates coated if has not use up after opened, the plate should be stored in Sealed bag.
2. washing buffer will Crystallization separation, it can be heated the water helps dissolve when dilute . Washing does not affect the result.
3. add Sample with sampler Each step, And proofread its accuracy frequently, avoids the experimental error. add sample within 5 mins, if the number of sample is much , recommend to use Volley .
4. if the testing material content is excessively higher（The sample OD is bigger than the first standard well ）,please dilute Sample （n-fold）, Please diluenteandmultiplied by the dilutionfactor.（×n×5）.
5. Closure plate membraneonly limits the disposable use, to avoidcross-contamination.
6. The substrate evade the light preservation.
7. Please according to use instruction strictly, The test result determination must take themicrotiter plate readeras a standard.
8. All samples, washing buffer ａnd each kind of reject should according to infective material process.
9. Do not mix reagents with those from other lots.
Take the standard density as thehorizontal, the OD value for thevertical,draw the standard curve ongraph paper,Find out the corresponding density according to the sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate the straight line regression equation of the standard curve with the standard density ａnd the OD value ,with the sample OD value in the equation, calculate the sample density, multiplied by the dilutionfactor, the result is the sample actual density. |
