大鼠白细胞介素1β（IL-1β）酶联免疫分析试剂盒使用说明书
本试剂仅供研究使用 目的：本试剂盒用于测定大鼠血清，血浆及相
关液体样本中白细胞介素1β（IL-1β）的含量。
实验原理：
本试剂盒应用双抗体夹心法测定标本中大鼠白细胞介素1β（IL-1β）水平。用纯化的大
鼠白细胞介素1β（IL-1β）抗体包被微孔板，制成固相抗体，往包被单抗的微孔中依次加
入白细胞介素1β（IL-1β），再与HRP 标记的白细胞介素1β（IL-1β）抗体结合，形成抗
体-抗原-酶标抗体复合物，经过彻底洗涤后加底物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白细胞介素1β（IL-1
β）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
大鼠白细胞介素1β（IL-1β）浓度。

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，在第一、第二孔中分别加标
准品100μl，然后在第一、第二孔中加标准品稀释液50μl，混匀；然后从第一孔、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30ng/L，20ng/L ，10 ng/L，5ng/L，2.5 ng/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（×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。
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。

and other biological fluids.
Principle of the assay
The kit assay Rat IL-1β level in the sample, use Purified Rat IL-1β antibody to coat
microtiter plate wells, make solid-phase antibody, then add IL-1β to wells, Combined IL-1β
antibody which With HRP labeled, become antibody -antigen -enzyme-antibody complex, after
washing Completely, Add TMB substrate solution,TMB substrate becomes blue color At HRP
enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the
color change is measured spectrophotometrically at a wavelength of 450 nm. The
concentration of IL-1β in the samples is then determined by comparing the O.D. of the samples
to the standard curve.

Assay procedure
1.Dilute and add sample to Standard: set 10 Standard wells on the ELISA plates coated, add
Standard 100μl to the first and the second well, then add Standard dilution 50μl to the first and
the second well, mix； take out 100μl form the first and the second well then add it to the third
and the forth well separately. then add Standard dilution 50μl to the third and the forth
well ,mix ； then take out 50μl from the third and the forth well discard, add 50μl to the fifth and
the sixth well ,then add Standard dilution 50μl to the fifth and the sixth well, mix ； take out 50μl
from the fifth and the sixth well and add to the seventh and the eighth well, then add Standard
dilution 50μl to the seventh and the eighth well ,mix ； take out 50μl from the seventh and the
eighth well and add to the ninth and the tenth well, add Standard dilution 50μl to the ninth and
the tenth well, mix , take out 50μl from the ninth and the tenth well discard(add Sample 50μl to
each well after Diluting ,(density: 30ng/L,20ng/L ,10 ng/L,5ng/L,2.5 ng/L)
2.add sample：Set blank wells separately (blank comparison wells don’t add sample and
HRP-Conjugate reagent, other each step operation is same). testing sample well. add Sample
dilution 40μl to testing sample well, then add testing sample 10μl (sample final dilution is
5-fold), add sample to wells , don’t touch the well wall as far as possible, and Gently mix.
3.Incubate: After closing plate with Closure plate membrane ,incubate for 30 min at 37℃.
4.Configurate liquid: 30-fold (or 20-fold)wash solution diluted 30-fold (or 20-fold) with distilled
water and reserve.
5.washing：Uncover Closure plate membrane, discard Liquid, dry by swing, add washing buffer
to every well, still for 30s then drain, repeat 5 times, dry by pat.
6.add enzyme：Add HRP-Conjugate reagent 50μl to each well, except blank well.
7.incubate：Operation with 3.
8.washing：Operation with 5.
9.color：Add Chromogen Solution A 50ul and Chromogen Solution B to each well, evade the
light preservation for 15 min at 37℃
10.Stop the reaction：Add Stop Solution50μl to each well, Stop the reaction(the blue color
change to yellow color).
11.assay：take blank well as zero , Read absorbance at 450nm after Adding Stop 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 diluente and multiplied by the dilution
factor.（×n×5）.
5. Closure plate membrane only limits the disposable use, to avoid cross-contamination.
6. The substrate evade the light preservation.
7. Please according to use instruction strictly, The test result determination must take the
microtiter plate reader as 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.
