超敏ECL化学发光液
| Western Blot结果的好坏与否与ECL发光液的选择有着密切关系,好的ECL发光液不仅可曝光得到漂亮的目的条带,还可节省昂贵的抗体。海基超敏ECL发光液用于Western、Northern和Southern blot分子杂交的化学发光检测,原理是采用新型发光底物(Luminol),其与辣根过氧化物酶反应时产生很强的发光信号,以此检测微量蛋白而获得理想的实验结果。比传统化学显色法灵敏度高,可达pg水平,发光持续时间长,信号30min内不会发生明显降低。 | ![]() |

文献和实验Ecl 显色原理:鲁米诺在免疫测定中既可用作标记物,也可用作过氧化物酶的底物。在Ecl底物中,含有H2O2和鲁米诺,在HRP(辣根过氧化物酶)的作用下,发出荧光来。 试验步骤: 1)将两种显色底物1:1等体积混合(一般各1ml/membrane)。 2)将混合物覆盖在膜表面,1-2分钟,摇晃使均匀。 3)用保鲜膜把膜包起来,放入夹板中。 4)在暗室中将X光片,覆盖在膜的上面,夹好夹子,曝光1min。 5)显影、定影。 6)根据结果调整曝光时间和曝光区域,得到
蛋白质免疫印迹(Western Blot )-底物化学发光 ECL 法
蛋白质免疫印迹(Western Blot )可以:(1)从蛋白质混合物中检出目标蛋白质;(2)定量或定性确定细胞或组织中蛋白质的表达情况;(3)用于蛋白质-蛋白质、蛋白质-DNA、蛋白质-RNA 相互作用后续分析。实验方法原理———底物化学发光 ECL 法Western 免疫印迹(Western Blot)是将蛋白质转移到膜上,然后利用抗体进行检测的方法。对已知表达蛋白,可用相应抗体作为一抗进行检测,对新基因的表达产物,可通过融合部分的抗体检测。与 Southern 或 Northern 杂交
过夜具体多长时间算合适,其实没有硬性规定; 二抗孵育的时间不宜过长,一般是室温下摇床孵育 1~2 小时,抗体孵育完成后要清洗干净,特别是二抗孵育完成后,否则可能导致显影结果出现高背景。 6、发光液配置 大部分实验室使用的 ECL 发光液,A 液和 B 液按照 1:1 的比例配置; 发光液要求现用现配,每次根据使用量合理配置用液量; 发光液配置时间过长同样会引起发光效果不好,背景脏或者漆黑一片。
