植物(Plant)脱镁螯合酶(MDCase)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
先包被脱镁螯合酶(MDCase)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*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
zui终的黄色。颜色的深浅和样品中的脱镁螯合酶(MDCase)呈正相
关。用酶标仪在450nm 波长下测定吸光度(OD 值),计算样品浓度。
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。
自备物品
1. 酶标仪(450nm)
2. 高精度加样器及枪头:0.5-10uL、2-20uL、20-200uL、200-1000uL
3. 37℃恒温箱
操作注意事项
1. 试剂盒保存在2-8℃,使用前室温平衡20 分钟。从冰箱取出的
浓缩洗涤液会有结晶,这属于正常现象,水浴加热使结晶*溶解
后再使用。
2. 实验中不用的板条应立即放回自封袋中,密封(低温干燥)保存。
3. 浓度为0 的S0 号标准品即可视为阴性对照或者空白;按照说明
书操作时样本已经稀释5 倍,zui终结果乘以5 才是样本实际浓度。
4. 严格按照说明书中标明的时间、加液量及顺序进行温育操作Materials supplied

Reagent preparation
20×wash solution:Dilute with Distilled or deionized water 1:20.
Assay procedure
1. Prepare all r e a g e n t s 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
1. 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.
