  试验原理：uPA-R试剂盒是固相夹心法酶联免疫吸附实验（ELISA）.已知uPA-R浓度的标准品、未知浓度的样品加入微孔酶标板内进行检测。先将uPA-R和生物素标记的抗体同时温育。洗涤后，加入亲和素标记过的HRP。再经过温育和洗涤，去除未结合的酶结合物，然后加入底物A、B，和酶结合物同时作用。产生颜色。颜色的深浅和样品中uPA-R的浓度呈比例关系。试剂盒内容及其配制试剂盒成份（2-8℃保存）96孔配置48孔配置配制96/48人份酶标板1块板（96T）半块板（48T）即用型塑料膜板盖1块半块即用型标准品：40ng/ml1瓶（0.6ml）1瓶（0.3ml）按说明书进行稀稀空白对照1瓶（1.0ml）1瓶（0.5ml）即用型标准品稀释缓冲液1瓶（4.0ml）1瓶（2.0ml）即用型生物素标记的抗uPA-R抗体1瓶（6.0ml）1瓶（3.0ml）即用型亲和链酶素-HRP1瓶（8.0ml）1瓶（4.0ml）即用型洗涤缓冲液1瓶（20ml）1瓶（10ml）按说明书进行稀释底物A1瓶（6.0ml）1瓶（3.0ml）即用型底物B1瓶（6.0ml）1瓶（3.0ml）即用型终止液1瓶（6.0ml）1瓶（3.0ml）即用型标本稀释液1瓶（12ml）1瓶（6.0ml）即用型自备材料1．蒸馏水。2．加样器：5ul、10ul、50ul、100ul、200ul、500ul、1000ul。3．振荡器及磁力搅拌器等。小鼠尿激酶型纤溶酶原激活物受体试剂盒安全性1．避免直接接触终止液和底物A、B。一旦接触到这些液体，请尽快用水冲洗。2．实验中不要吃喝、抽烟或使用化妆品。3．不要用嘴吸取试剂盒里的任何成份。操作注意事项1．试剂应按标签说明书储存，使用前恢复到室温。稀稀过后的标准品应丢弃，不可保存。2．实验中不用的板条应立即放回包装袋中，密封保存，以免变质。3．不用的其它试剂应包装好或盖好。不同批号的试剂不要混用。保质前使用。4．使用一次性的吸头以免交叉污染，吸取终止液和底物A、B液时，避免使用带金属部分的加样器。5．使用干净的塑料容器配置洗涤液。使用前充分混匀试剂盒里的各种成份及样品。6．洗涤酶标板时应充分拍干，不要将吸水纸直接放入酶标反应孔中吸水。7．底物A应挥发，避免长时间打开盖子。底物B对光敏感，避免长时间暴露于光下。避免用手接触，有毒。实验完成后应立即读取OD值。8．加入试剂的顺序应一致，以保证所有反应板孔温育的时间一样。9．按照说明书中标明的时间、加液的量及顺序进行温育操作。样品收集、处理及保存方法1、血清-----操作过程中避免任何细胞刺激。使用不含热原和内毒素的试管。收集血液后，1000×g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、肝素血浆可用于检测。1000×g离心30分钟去除颗粒。3、细胞上清液---1000×g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。1000×g离心10分钟，取上清液5、保存------如果样品不立即使用，应将其分成小部分-70℃保存，避免反复冷冻。尽可能的不要使用溶血或高血脂血。如果血清中大量颗粒，检测前先离心或过滤。不要在37℃或更高的温度加热解冻。应在室温下解冻并确保样品均匀地充分解冻。小鼠尿激酶型纤溶酶原激活物受体试剂盒试剂的准备1．标准品：标准品的系列稀释应在实验时准备，不能储存。稀释前将标准品振荡混匀。稀释比例按下表中进行：40ng/ml（6号标准品）原倍浓度不用稀释直接加入50ul。20ng/ml（5号标准品）100ul的原倍标准品加入100ul的标准品稀释液10ng/ml（4号标准品）100ul的5号标准品加入100ul的标准品稀释液5.0ng/ml（3号标准品）100ul的4号标准品加入100ul的标准品稀释液2.5ng/ml（2号标准品）100ul的3号标准品加入100ul的标准品稀释液1.25ng/ml（1号标准品）100ul的2号标准品加入100ul的标准品稀释液0ng/ml（空白对照）原始浓度不用稀释直接加入50ul。2．洗涤缓冲液（50×）的稀释：蒸馏水50倍稀释。操作步骤1．使用前，将所有试剂充分混匀。不要使液体产生大量的泡沫，以免加样时加入大量的气泡，产生加样上的误差。2．根据待测样品数量加上标准品的数量决定所需的板条数。每个标准品和空白孔建议做复孔。每个样品根据自己的数量来定，能使用复孔的尽量做复孔。标本用标本稀释液1：1稀释后加入50ul于反应孔内。3．加入稀释好后的标准品50ul于反应孔、加入待测样品50ul于反应孔内。立即加入50ul的生物素标记的抗体。盖上膜板，轻轻振荡混匀，37℃温育1小时。4．甩去孔内液体，每孔加满洗涤液，振荡30秒，甩去洗涤液，用吸水纸拍干。重复此操作3次。如果用洗板机洗涤，洗涤次数增加一次。5．每孔加入60ul的亲和链酶素-HRP，轻轻振荡混匀，37℃温育30分钟。6．甩去孔内液体，每孔加满洗涤液，振荡30秒，甩去洗涤液，用吸水纸拍干。重复此操作3次。如果用洗板机洗涤，洗涤次数增加一次。7．每孔加入底物A、B各50ul，轻轻振荡混匀，37℃温育10分钟。避免光照。8．取出酶标板，迅速加入50ul终止液，加入终止液后应立即测定结果。9．在450nm波长处测定各孔的OD值。建议使用的实验方案标准品浓度（ng/ml）A4040样品样品样品样品样品样品样品样品样品样品B2020样品样品样品样品样品样品样品样品样品样品C1010样品样品样品样品样品样品样品样品样品样品D5.05.0样品样品样品样品样品样品样品样品样品样品E2.52.5样品样品样品样品样品样品样品样品样品样品F1.251.25样品样品样品样品样品样品样品样品样品样品G00样品样品样品样品样品样品样品样品样品样品H样品样品样品样品样品样品样品样品样品样品样品样品局限6号标准品以上的结果为非线性的，根据此标准曲线无法得到极ng确的结果。试剂盒性能1.灵敏度：Z小的检测浓度小于1号标准品。稀释度的线性。样品线性回归与预期浓度相关系数R值为0.990。2.特异性：不与其它细胞因子反应。3.重复性：板内、板间变异系数均小于10%。小鼠尿激酶型纤溶酶原激活物受体试剂盒结果判断与分析1、仪器值：于波长450nm的酶标仪上读取各孔的OD值2、以吸光度OD值为纵坐标（Y），相应的uPA-R标准品浓度为横坐标（X），做得相应的曲线，样品的uPA-R含量可根据其OD值由标准曲线换算出相应的浓度。3、检测值范围：0-40ng/ml4、敏感度：0.1ng/ml[详细]

• 人纤溶酶原（Plasminogen）ELISA试剂盒说明书

  电话：021-6533363955229872网址：http://www.westang.com人纤溶酶原（Plasminogen）ELISA试剂盒（用于血清、血浆、细胞培养上清液和尿液生物体液内）原理本实验采用双抗体夹心ABC-ELISA法。用抗人Plasminogen单抗包被于酶标板上，标准品和样品中的Plasminogen与单抗结合，加入生物素化的抗人Plasminogen，形成免疫复合物连接在板上，辣根过氧化物酶标记的Streptavidin与生物素结合，加入底物工作液显蓝色，Z后加终止液硫酸，在450nm处测OD值，Plasminogen浓度与OD值成正比，可通过绘制标准曲线求出标本中Plasminogen浓度。试剂盒组成（2-8℃保存）酶标板（CoatedWells）96孔酶标抗体工作液（EnzymeConjugate）12ml10×标本稀释液（SampleBuffer）12ml20×浓缩洗涤液（WashBuffer）50ml标准品（Standards）：2000ng/瓶2瓶底物工作液（TMBSolution）12ml**抗体工作液（BiotinylatedAntibody）12ml终止液（StopSolution）12ml准备试剂与收集血样1.收集标本：血清、血浆、细胞培养上清液等尽早检测，2-8℃保存48小时；更长时间须冷冻（-20℃或-70℃）保存，避免反复冻融。血清、血浆、细胞培养上清至少作1：1000-10000倍稀释（取10ul，加标本稀释液990ul,稀释100倍，然后再取前液10ul,加标本稀释液990ul，此时一共稀释了10000倍）。尿液不用稀释直接检测。2.标准品液配制：使用前加入1ml蒸馏水混匀，配成2000ng/ml的溶液。设标准管8管，**管加标本稀释液900ul，第二至第八管加入标本稀释液500ul。在**管中加入2000ng/ml的标准品溶液100ul混匀后用加样器吸出500ul，移至第二管。如此反复作对倍稀释，从第七管中吸出500ul弃去。第八管为空白对照。3.10×标本稀释液用蒸馏水作1:10倍稀释（示例：1ml浓稀释液+9ml蒸馏水）。4.洗涤液：用重蒸水1:20稀释（示例：1ml浓缩洗涤液加入19ml的重蒸水）检测程序1.加样：每孔各加入标准品或待测样品100ul，将反应板充分混匀后置37℃120分钟。2.洗板：用洗涤液将反应板充分洗涤4-6次，向滤纸上印干。3.每孔中加入**抗体工作液100ul。将反应板充分混匀后置37℃60分钟。4.洗板：同前。5.每孔加酶标抗体工作液100ul。将反应板置37℃30分钟。6.洗板：同前。7.每孔加入底物工作液100ul，置37℃暗处反应15分钟。8.每孔加入100ul终止液混匀。9.30分钟内用酶标仪在450nm处测吸光值。结果计算与判断1.所有OD值都应减除空白值后再行计算。2.以标准品200、100、50、25、12.5、6.25、3.12、0ng/ml为横坐标，OD值为纵坐标，在坐标纸上作图，画出标准曲线。3.根据样品OD值在该曲线图上查出相应Plasminogen含量，再乘上稀释倍数即可。试剂盒性能1.灵敏度：Z小的Plasminogen检测浓度小于1.5ng/ml。2.特异性：可同时检测重组或天然的人Plasminogen。不与人其它细胞因子有交叉反应。3.重复性：板内、板见变异系数均小于10％。注意事项1.以上标准孔及待测样品均建议做复孔，每次测定应同时做标准曲线。2.洗涤过程很关键。洗涤不充分将导致极ng确度误差及OD值错误地升高。3.板条开封后剩余板条要再封好，保持板条干燥。4.本试剂盒宜置4oC冰箱保存。5.本试剂盒仅用于科研，不能用于临床诊断！[详细]
