克伦特罗（Clenbuterol）定量检测试剂盒（ELISA）
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)
Materials supplied
Note: Standard concentration was followed by:
500、250、125、62.5、31.25、0 ng/mL.
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 1.0 ng/mL.

简介：克伦特罗（Clenbuterol）属于beta兴奋剂，是一种高选择性的兴奋剂和激素，具有水解脂肪、合成代谢和对非条纹肌肉组织的松弛作用。进年来被一些人非法添加到饲料中以提高脂肪型动物的瘦肉率和加速动物的生长。当用作生长调节剂时，其添加量是治疗量的5—10倍，常在动物体内残留而给消费者带来危害。 通常，HPLC或GC-MS是克伦特罗残留检测的确证方法，但是其前处理步骤费用昂贵，而ELISA快速检测试剂盒因成本低、操作简便、速度快、一次检测样本量大、仪器化低，现已成为常规的筛选
剂的初筛2001年12月21日国家质量监督检验检疫总局推荐英国Randox公司生产的ELISA试剂盒为我国检测动物激素和抗生素残留的首选筛选试剂。目前用于饲料中违禁药品和添加剂筛检的商品化试剂盒有许多，例如德国r-Biopharm公司，意大利Tecna及美国Idexx公司的产品等，它们在饲料安全检测中发挥着重要的作用。本文仅以ELISA试剂盒筛检盐酸克伦特罗为例做一介绍。 盐酸克伦特罗简称克伦特罗（CL），因其对人类健康的极大危害，被严格禁止在饲料中添加。目前ELISA试剂盒已广泛用于饲料
