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。
- 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)。

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)

Reagent preparation
20×wash solution:Dilute with Distilled or deionized water 1:20.
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 ng/ml.

cathy12303 有没有哪位前辈用过cAMP的ELISA试剂盒? dianaofyezi 我 有问题可以站内消息或者QQ52187644联系。 白大褂2009 你好,我是新手,你用过的ELISA试剂在哪买的,哪个公司的比较好啊?还有,测定大鼠脑组织里的cAMP,放免法和ELISA法各有什么优缺点啊?谢谢回复!! songdianwei 我在 R&D公司买的,测
组织充分那就可以用这些试剂盒检测。 当然,不同公司cAMP试剂盒灵敏度有些差异,这个也需要做好选择。 另外,选择这些试剂盒时还需要根据自己实验室的仪器配置来选择,例如Cisbio,跟PE公司的cAMP试剂盒是基于TR-FRET方法的,因此酶标仪必须有TRF跟FRET功能;Promega公司的试剂盒是化学发光的,因此仪器上需要有Luminescence; DiscoverX的试剂盒也是测的Luminescence;其他一些公司就是Elisa试剂盒,这个大家就比较
