1、小鼠活化部分凝血活酶时间(APTT)ELISA检测试剂盒简介说明小鼠(Mouse)活化部分凝血活酶时间(APTT)ELISA检测试剂盒使用说明书本试剂盒只能用于科学研究,不得用于医学诊断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)o往预先包被活化部分凝血活酶时间(APTT)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di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活化部分凝血活酶时间(APTT)呈正相关。用酶标仪在45Onnl波长下测定吸光度(OD值),计算样品浓度。样品收
2、集、处理及保管方法1 .血清:使用不含热原和内毒素的试管,操作过程中避开任何细胞刺激,收集血液后,3000转离心10分钟将血清和红细胞快速小心地分别。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 .保管:假如样本收集后不及时检测,请按一次用量分装,冻存于2(C,避开反复冻融,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(45Onin)2 .高精度加样器及枪头:0.510uL.220uL、20200uL.2001000uL
3、3.37。C恒温箱操作注意事项1 .试剂盒保管在28P,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Wan全溶解后再使用。2 .试验中不用的板条应立刻放回自封袋中,密封(低温干燥)保管。3 .浓度为0的SO号标准品即可视为阴性对照或者空白;依照说明书操作时样本已经稀释5倍,最结束果乘以5才是样本实际浓度。4 .严格依照说明书中标明的时间、加液量及次序进行温育操作。5 .全部液体组分使用前充分摇匀。试剂盒构成名称96孔配置48孔配置备注微孔酶标板12孔X8条12孔X4条无标准品O.3mL*6管0.3mL*6管无样本稀释液6mL3mL无检测抗体HRPIO

5、密封放回4o2 .设置标准品孔和样本孔,标准品孔各加不同浓度的标准品50L;3 .样本孔先加待测样本IOUL,再加样本稀释液40RL;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100RL,用封板膜封住反应孔,37。C水浴锅或恒温箱温育60mino5 .弃去液体,吸水纸上拍干,每孔加满洗涤液,静置InIin,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50RL,37避光孵育15min7 .每孔加入停止液50uL,15min内,在45Onm波优点测定各孔的OD值。结果推断绘制标准曲线:在EXCel工作
6、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。试剂盒性能1 .准确性:标准品线性回归与预期浓度相关系数R值,大于等于0.9900.2 .灵敏度:最di检测浓度小于1.0pgmlo3 .特异性:不与其它可溶性结构仿佛物交叉反应。4 .重复性:板内、板间变异系数均小于15虬5 .贮藏:28,避光防潮保管。6 .有效期:6个月免责声明1 .试剂盒仅供研究使用,不得用于临床试验或人体试验,否则所产生的一切后果,由试验者承当,本公司概不负责。2 .严格依照说明书操作,试验者违反说明书操作,后果由试验者承当。FORRESEARCHUSEONLY.NO
