人（Human）8羟基脱氧鸟苷（8-OHdG）ELISA 检测试剂盒
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8羟基脱氧鸟苷（8-OHdG）捕获抗体的包被微孔中，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，TMB在过氧化物酶的催化下转化成蓝，并在酸的作用下转化成最终的黄。颜的深浅和样品中的8羟基脱氧鸟苷（8-OHdG）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.
横隔板血清：使用不含热原和内毒素的试管，操作过程中避免任何细
胞刺激，收集血液后，3000转离心10分钟将血清和红细胞迅速小心地分离。2.血浆：EDTA、柠檬酸盐或肝素抗凝。3000转离心30分钟取上清。3.细胞上清液：3000转离心10分钟去除颗粒和聚合物。4.
组织匀浆：将组织加入适量生理盐水捣碎。3000转离心10分钟
取上清。5.

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，水浴加热使结晶完全溶解后再使用。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，最终结果乘以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。5
所有液体组分使用前充分摇匀。

注：标准品（S0-S5）浓度依次为:0、20、40、80、160、320pg/mL.
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1.
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。2.
自动洗板机：每孔注入洗液350μL，浸泡1min，洗板5次。
操作步骤1.
从室温平衡20min 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℃。2.设置标准品孔和样本孔，标准品孔各加不同浓度的标准品50μ
L；3.
待测样本孔先加待测样本10μL，再加样本稀释液40μL(即样本稀释5倍)；空白孔不加。4.
除空白孔外，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。5.
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）。6.每孔加入底物A、B 各50μL，37℃避光孵育15min。
7.
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。

ELISA Kit instruction
Intended use
This 8-OHdG 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 450nm using a spectrophotometer.In order to measure the concentration of 8-OHdG in the sample,this 8-OHdG 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 8-OHdG concentration.The concentration of 8-OHdG in the samples is then determined by comparing the O.D.of the samples to the standard curve.
Sample collection and storages
Serum -Use a serum separator tube and allow samples to clot for 30minutes
before centrifugation for 10minutes 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 30minutes at 3000×g at 2-8℃within 30minutes 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 shoule be centrifugated dequately and no hemolysis or
granule was allowed.

Assay procedure
之文界1.
Prepare all re 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 60minutes 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 15minutes at 37°C.Protect from light.
