人（Human）20S蛋白酶体（20SP）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20S蛋白酶体（20SP）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终的黄色。颜色的深浅和样品中的20S蛋白酶体（20SP）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.  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，终结果乘以5才是样本实际浓度。

　　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Ψ 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。

Human 20S proteasome(20SP)ELISA Kit instruction

　　Intended use

　　This 20SPELISA 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 concentration of 20SPin the sample, this 20SPELISA 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 20SPconcentration. The concentration of 20SPin the samples is then determined by comparing the O.D. of the samples to the standard curve.

　　Samplecollection 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 30minutes 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 shoule be centrifugated dequately and no hemolysis or granule was allowed.

　　Assay procedure

　　1. Prepare allreagentsbeforestartingassayprocedure.ItisrecommendedthatallStandardsand Samplesbe addedin duplicateto the MicroelisaStripplate.

　　2. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.

　　3.  Add Sample: Add testing sample10μl then add 40μl of Sample Diluent to testing sample well; Blank welldoesn’t add anyting.

　　4.  Add100μlofHRP-conjugate reagentto each well,cover with anadhesive stripandincubatefor60 minutesat37°C.

　　5. Aspirate each well and wash, repeating the process fourtimes for a total of five washes.Wash by filling each well with Wash Solution(400μl) using a squirt bottle, manifolddispenseror autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solutionby aspirating ordecanting. 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 toyellow. 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. ReadtheOpticalDensity(O.D.)at450nmusinga microtiterplatereaderwithin15minutes.

　　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.

　　2. 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.

　　3. 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.

　　4. 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.

　　5. The sensitivity by this assay is10pg/ml

　　6. Standard curve

　　Storage：  2-8℃.

　　validity：six months.
