western－blotting－的过程和原理
什么理论过程？就是原理呗？WesternBlot原理、显色分类及操作步骤一、原理与Southern或Northern杂交方法类似，但WesternBlot采用的是聚丙烯酰胺凝胶电泳，被检测物是蛋白质，“探针”是抗体，“显色”用标记的二抗。经过PAGE分离的蛋白质样品，转移到固相载体（例如硝酸纤维素薄

蛋白质印迹（Western－blotting）
印迹法（blotting）是指将样品转移到固相载体上，而后利用相应的探测反应来检测样品的一种方法。1975年，Southern建立了将 DNA转移到硝酸纤维素膜（NC膜）上，并利用DNA－RNA杂交检测特定的DNA片段的方法，称为Southern印迹法。而后人们用类似的方法，对 RNA和蛋白

western－blotting的一些个人经验
个人经验,仅供参考:1.用脱脂奶粉封闭的效果不一定比用BSA差,不过我们试过几种奶粉,有一些奶粉不太适合.推荐使用的奶粉:雀巢高钙奶粉,多力精低脂奶粉.一般国产的奶粉的颗粒比较大,不太容易溶解.2.关于三名治:本人以前做时花很多时间在防止短路上,现在我做的时候根本没有剪齐,最主要的是赶气泡,这是关键

western－blotting转膜是根据什么原理
原理：westernblotting转膜一般采用“滤纸-凝胶-膜-滤纸”夹心法，凝胶靠近负极，膜靠近正极。因为蛋白上结合有sds，因而带负电，在电流的作用下会从负极向正极运动，从而转移到膜上。
Western－blotting电泳免疫印迹简单原理
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。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。Western Blot是检测单一细胞蛋白表达量最好的方法；若要对表达蛋白进行细胞定位，confocal应是首选的方
western－blotting－分离胶浓度是如何计算
WESTERN技术中，分离胶的浓度是按聚丙烯酰胺的浓度来计算的。一般先配置30%的丙叉-亚甲叉母液，以配置10%浓度的分离胶10毫升为例，则需要30%的母液为（10%/30%）*10毫升。反过来，只要你知道用多少毫升30%的母液时，就能推算出胶的浓度了。

荧光检测的优势 精确的western blot蛋白定量，要求在宽泛的范围内信号与蛋白浓度呈现线性变化。 对于化学发光检测方法，虽然灵敏度极高，但由于其原理是酶促反应，信号随时间变化，重复性差。 荧光检测是定量western blot的“金标准”。信号强度与结合在靶标蛋白上的抗体
