DNA pulldown是一種用于研究DNA與蛋白質互作的技術。通常用來分析目標基因調控區域相結合的轉錄因子及其他調控蛋白。 (本試劑盒僅供科研用途)
實驗原理:
針對目標區域設計生物素標記的特異性DNA探針偶聯磁珠,并與細胞核提取物孵育。蛋白分子與DNA探針特異性結合,通過洗脫,得到目的DNA探針-蛋白質復合物。最后采用Western Blot或質譜鑒定蛋白質類型。
產品優勢:
1.自主品牌:擁有自主知識產權專利。
2.快速省時:從標記探針到結果分析,所費時間顯著減少。
3.穩定可靠:DNA末端標記生物素,不影響蛋白結合位點。標記好的DNA可以保存一年。
4.配備完整:只需要自備生物素末端標記的DNA探針及核蛋白質樣品。
5.可得到完整、高濃度蛋白,用于質譜檢測。
