植物(Plant)β-1,3-葡聚糖酶(β-1,3-glucanase)ELISA检测试剂盒使用说明书
检测原理
试剂盒采用双抗体一步夹心法酶联免疫吸附试验(ELISA)。往预先包被β-1,3-葡聚糖酶(β-1,3-glucanase)抗体的包被微孔中,依次加入标本、标准品、HRP标记的检测抗体,经过温育并彻底洗涤。用底物TMB显色,TMB在过氧化物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β-1,3-葡聚糖酶(β-1,3-glucanase)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD 值),计算样品活性。
样品收集、处理及保存方法
1. 样本不能含叠氮钠(NaN3),因为叠氮钠(NaN3)是辣根过氧化物酶(HRP)的抑制剂。
2. 标本采集后尽早进行提取,提取按相关文献进行。
3. 植物萃取液或其它相关样本:请1000 x g离心20分钟,取上清即可检测。
4. 保存:如果样本收集后不及时检测,请按一次用量分装,冻存于-20℃,避免反复冻融,在室温下解冻并确保样品均匀地充分解冻。

Plant β-1,3-glucanase ELISA Kit instruction
Intended use
This β-1,3-glucanase ELISA kit is intended Laboratory for Research use only and is not for use in diagnostic or therapeutic procedures.The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the activity of β-1,3-glucanase in the sample, this β-1,3-glucanase ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus β-1,3-glucanase activity. The activity of β-1,3-glucanase in the samples is then determined by comparing the O.D. of the samples to the standard curve.
Sample collection and storages
2. Extract as soon as possible after Specimen collection, Extracted According to the relevant literature.
Cell culture supernates and plant exact fluids - Remove particulates by centrifugation and assay immediately or aliquot and store samples at -20°C or -80°C. Avoid repeated freeze-thaw.
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.
