    Azure-biosystems-定量Western-Blotting熒光檢測優勢

      熒光檢測的優勢   精確的western blot蛋白定量,要求在寬泛的范圍內信號與蛋白濃度呈現線性變化。   對于化學發光檢測方法,雖然靈敏度極高,但由于其原理是酶促反應,信號隨時間變化,重復性差。   熒光檢測是定量western blot的“金標準”。信號強度與結合在靶標蛋白上的抗體

    western-blotting的一些個人經驗

    個人經驗,僅供參考:1.用脫脂奶粉封閉的效果不一定比用BSA差,不過我們試過幾種奶粉,有一些奶粉不太適合.推薦使用的奶粉:雀巢高鈣奶粉,多力精低脂奶粉.一般國產的奶粉的顆粒比較大,不太容易溶解.2.關于三名治:本人以前做時花很多時間在防止短路上,現在我做的時候根本沒有剪齊,最主要的是趕氣泡,這是關鍵

    western-blotting-分離膠濃度是如何計算

    WESTERN技術中,分離膠的濃度是按聚丙烯酰胺的濃度來計算的。一般先配置30%的丙叉-亞甲叉母液,以配置10%濃度的分離膠10毫升為例,則需要30%的母液為(10%/30%)*10毫升。反過來,只要你知道用多少毫升30%的母液時,就能推算出膠的濃度了。

    Western-blotting電泳免疫印跡簡單原理

    免疫印跡(Western Blot)是將蛋白質轉移到膜上,然后利用抗體進行檢測。對已知表達蛋白,可用相應抗體作為一抗進行檢測,對新基因的表達產物,可通過融合部分的抗體檢測。Western Blot是檢測單一細胞蛋白表達量最好的方法;若要對表達蛋白進行細胞定位,confocal應是首選的方

    western-blotting轉膜是根據什么原理

    原理:westernblotting轉膜一般采用“濾紙-凝膠-膜-濾紙”夾心法,凝膠靠近負極,膜靠近正極。因為蛋白上結合有sds,因而帶負電,在電流的作用下會從負極向正極運動,從而轉移到膜上。
