等等pull down assay 的实验原理，虽然这些是针对蛋白的，但是原属理一样，很简单的，记得做好control就...
DNA probe 和链霉亲和素杂交在一起,而链霉亲和素能够和magnetic beads亲和结合,所以经过孵育之后,再将细胞核提取物流过beads,DNA probe是400bp的,所以和目的DNA结合力相当高,就将目的DNA留在beads里面,其他不能结合的就都被去除.最后,在用专门的洗脱液(对应于链霉亲和素)进行洗脱,得到目的DNA.你可以看看 GST-ta...

如题 DNA-affinity pull-down assay，翻译成中文，标准的翻译是什么？谢谢！
d, Differential analysis of proteins enriched in NF-κB DNA affinity pull-down +TNF-α vs. -TNF-α, color codes are as indicated in a. Horizontal dotted line indicates FDR 0.25. e, PROBER vs. DNA pull-down (–TNF-α) fold-change scatter plot; blue dots indicate proteins enriched (...
简言之,chip是拉下试验(pull-downassay),其依赖于通过机械、物理、化学或酶法剪切使活生物体的基因组物质片段化以产生蛋白质-dna片段池(主要为核小体),然后用亲和剂例如结合特定蛋白或其翻译后修饰的抗体探测(probed)所述蛋白质-dna片段池以拉下特定染色质片段。chip利用从片段化的染色质“输入”库进行的亲和...
b Affinity pulldown utilizing nickel-NTA resin to examine the interaction of (His)6-tagged Dna2 and dna2-AC with RPA. The supernatant (S), wash (W), and eluate (E) fractions were analyzed by SDS-PAGE. The experiments were carried out once. c Formation of ternary complex from titrated...
To test this possibility, we performed affinity enrichment (“pulldown”) experiments with a version of hpol η1–437 that retained the GST tag (Fig. 7). WRN proteins were incubated with either GST-hpol η1–437 bound or empty glutathione-Sepharose beads. After washing the resin, the ...
蛋白质与蛋白质DNA相互作用研究方法加实例 课件.ppt,3.4 GST pull-down技术优缺点 优点: 融合蛋白亲具有高通量性、高选择性的特点,由于融合蛋白的多样性以及表达系统的多样性(如细菌、果蝇、哺乳动物),该方法能够研究蛋白质在复杂体系中的相互作用。 缺点: 该方法的成功
(25 mM Tris-HCl, pH 7.5, 10% glycerol, 0.5 mM EDTA, 50 mM KCl, 1 mM DTT, 0.01% Igepal) on ice for 2 h. Then, 15 μL of anti-Flag M2 affinity beads or amylose beads were added to the solution mixture to pull down the target protein. After an additional 3 ...
