试剂的准备
20×洗涤缓冲液的稀释：蒸馏水按1：20稀释，即1份的20×洗涤缓冲液加19份的蒸馏水。
洗板方法

手工洗板：甩尽孔内液体，每孔加满洗涤液，静置1min后甩尽孔内液体，在吸水纸上拍干，如此洗板5次。
自动洗板机：每孔注入洗液350μL，浸泡1min，洗板5次。

操作步骤

从室温平衡60min后的铝箔袋中取出所需板条，剩余板条用自封袋密封放回4℃。
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；
待测样本孔先加待测样本10μL，再加样本稀释液40μL；
随后标准品孔和样本孔中每孔加入辣根过氧化物酶（HRP）标记的检测抗体100μL，用封板膜封住反应孔，37℃水浴锅或恒温箱温育60min。
弃去液体，吸水纸上拍干，每孔加满洗涤液，静置1min，甩去洗涤液，吸水纸上拍干，如此重复洗板5次（也可用洗板机洗板）。
每孔加入底物A、B各50μL，37℃避光孵育15min。
每孔加入终止液50μL，15min内，在450nm波长处测定各孔的OD值。

结果判断
绘制标准曲线：在Excel工作表中，以标准品浓度作横坐标，对应OD值作纵坐标，绘制出标准品线性回归曲线，按曲线方程计算各样本浓度值。

　在ELISA实验前的注意事项1 仔细阅读说明书2 确定试剂盒在有效期内3 按说明书确定所有试剂齐全（数量、体积）4 标本制备要规范，每份标本体积要按2-3个复孔以上的量制备（贮存），尽量分装做备份。短期内无法实验者，注意低温保存5 准备好所有实验额外所需物品，如试管、吸头、移液器、离心机等6 根据检测标本数量确定所需试剂的量7 按说明书将所用试剂平衡至室温，配制所需试剂DIY夹心法ELISA常见技术指南8 选择抗体时最好选择一个单抗和一个多抗进行配对；若选择两个单抗，必须识别不同表位的抗体；最好从同一家公司选择抗体对。9 ELISA实验中为了确定最佳信号和最低背景应将捕获抗体（0.5-4μg/ml）和检测抗体（0.25-2μg/ml）在预实验中进行彼此相抗的滴定。同时，应包括在适当范围内的标准品的系列稀释。按试剂说明书常规提供的范围进行操作。10 标准品的配制：对于每种细胞因子应仔细阅读说明书，注意每批的细节。在使用细胞因子前，瞬时离心试剂瓶，尽可能多地收回其中的细胞因子。根据每批说明书中的细节，将冻干的细胞因子复溶。11 一般待测抗原标准曲线的线性范围的可通过将标准品做8次2倍系列稀释从2000pg/ml 到15pg/ml。可利用标准的ELISA操作流程、放大试剂盒、第三类试剂、或改变酶底物系统可在一定范围内提高灵敏度。12 为了优化灵敏度，建议过夜孵育标准品和标本。13 若使用过氧化物酶作为显色系统，应严禁在洗液和稀释液中加die氮钠，die氮钠可抑制过氧化物酶的活性。14 当测定混合液体中的抗原时，如血清，建议在标本稀释液中加不相干的Ig. 每个试剂盒操作是不同的，请按说明书操作。具体事项请来电咨询

Sample collection and storages
Serum - Use a serum separator tube and allow samples to clot for 30 minutes before centrifugation for 10 minutes at approximately 3000×g. Remove serum and assay immediately or aliquot and store samples at -20℃ or -80℃.Avoid repeated freeze-thaw cycles
Plasma - Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 30 minutes at 3000×g at 2-8℃ within 30 minutes of collection. Store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.
Cell culture supernates and other biological fluids - Remove particulates by centrifugation and assay immediately or aliquot and store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.
Note: The samples should be centrifugated adequately and no hemolysis or granule was allowed.
Materials required but not supplied
1. Standard microplate reader(450nm)
2. Precision pipettes and Disposable pipette tips.
3. 37 ℃ incubator
Precautions
1. Do not substitute reagents from one kit to another. Standard, conjugate and microplates are matched for optimal performance. Use only the reagents supplied by manufacturer.
2. Do not remove microplate from the storage bag until needed. Unused strips should be stored at 2-8°C in their pouch with the desiccant provided.
3. Mix all reagents before using.
Remove all kit reagents from refrigerator and allow them to reach room temperature ( 20-25°C)

Assay procedure
1. Prepare all reagents before starting assay procedure. It is recommended that all Standards and Samples be added in duplicate to the Microelisa Stripplate.
2. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.
3. Add Sample: Add testing sample 10μl Then add sample diluent 40μl to testing sample well; Blank well doesn’t add anyting.
4. Add 100μl of HRP-conjugate reagent to each well, cover with an adhesive strip and incubate for 60 minutes at 37°C.
5. Aspirate each well and wash, repeating the process four times for a total of five washes. Wash by filling each well with Wash Solution (400μl) using a squirt bottle, manifold dispenser or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting. Invert the plate and blot it against clean paper towels.
6. Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix and incubate for 15 minutes at 37°C. Protect from light.
7. Add 50μl Stop Solution to each well. The color in the wells should change from blue to yellow. If the color in the wells is green or the color change does not

appear uniform, gently tap the plate to ensure thorough mixing.
8. Read the Optical Density (O.D.) at 450 nm using a microtiter plate reader within 15 minutes.
Calculation of results

This standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average O.D. (450 nm) obtained for each of the six standard concentrations on the vertical (Y) axis versus the corresponding concentration on the horizontal (X) axis.
First, calculate the mean O.D. value for each standard and sample. All O.D. values, are subtracted by the mean value of the zero standard before result interpretation. Construct the standard curve using graph paper or statistical software.
To determine the amount in each sample, first locate the O.D. value on the Y-axis and extend a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration.
Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in result. Each user should obtain their own standard curve.
The sensitivity by this assay is 0.1 nmol/L.
