绵羊*（Cortisol）酶联免疫分析（ELISA）
绵羊*（cortisol）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：本试剂盒用于测定绵羊血清、血浆、组织匀浆及相关液体样本中*（cortisol）的含量。
实验原理：
本试剂盒应用双抗体夹心法测定标本中绵羊*（cortisol）水平。用纯化的绵羊*（cortisol）捕获抗体包被微孔板，制成固相抗体，往包被的微孔中依次加入绵羊*（cortisol），再与hrp标记的检测抗体结合，形成抗体-抗原-酶标抗体复合物，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终的黄色。颜色的深浅和样品中的绵羊*（cortisol）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绵羊*（cortisol）含量。

注：标准品浓度依次为：160、80、40、20、10、0 ng/ml.
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
标准品的加样：设置标准品孔和样本孔，标准品孔各加不同浓度的标准品50μl；。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。加酶：每孔加入酶标试剂100μl，空白孔除外。温育：用封板膜封板后置37℃温育60分钟。配液：将20倍浓缩洗涤液用蒸馏水20倍稀释后备用。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。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.终止：每孔加终止液50μl，终止反应（此时蓝色立转黄色）。测定：以空白孔调零，450nm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：
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。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。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。一次加样时间控制在5分钟内，如标本数量多，*使用排枪加样。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，计算时请后乘以总稀释倍数（×n×5）。封板膜只限一次性使用，以避免交叉污染。底物请避光保存。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.所有样品，洗涤液和各种废弃物都应按传染物处理。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。
