GST pull down(GST融合蛋白沉降技术)是体外检测蛋白相互作用的常用方法,一般来说,GST融合蛋白pull down方法用于两个方面:一是鉴定能与已知融合蛋白相互作用的未知蛋白质;二是鉴定两个已知蛋白质之间是否存在相互作用。为排除假阳性所设的一组对照实验是在没有诱饵蛋白存在的条件下,将样品结合到GST上。该对照可以是表...
A:细胞、动物/植物组织、菌体都可以做DNA pull down, 我们还可以做的检测实验具体如下: (1) RNA-蛋白/RNA互作及定位:RNA pull down、RIP、fish等; (2) DNA-蛋白互作:DNA pull down、ChIP、EMSA、双荧光素酶、酵母单杂等; (3) 蛋白-蛋白互作:GST/his pull down、CoIP、酵母双杂等; (4) 细胞学检测:...
Epitope-tagged proteinProtein pulldown assayRNA degradosomeRNase EThe method of co-immunoprecipitation (co-IP or pulldown) enables the identification of proteins interacting in macromolecular assemblies, through the purification of a key protein by affinity chromatography using specific antibodies immobilized...
Determining protein partners is an essential step toward understanding protein function and identifying relevant biological pathways. Many methods exist for investigating protein–protein interactions. The pull-down assay is an in vitro technique used to detect physical interactions between two or more prot...
Pull Down Assay GST Pull Down Pull down技术的基本原理是 将一种蛋白质固定于某种基质上(如Sepharose),但细胞抽提液经过该基质时,可与该固定蛋白相互作用的配体蛋白被吸附,而没有被吸附的“杂质”则随洗脱液流出。 被吸附的蛋白可以通过改变洗脱液或洗脱条件而回收下来。通过pull down技术可以确定已知的蛋白与钓...
The pull-down assay is an in vitro technique used to detect physical interactions between two or more proteins and an invaluable tool for confirming a predicted protein-protein interaction or identifying novel interacting partners. This method typically involves the use of affinity purification with ...
1. RNA Pull Down Assay(1) 为了鉴定特定的RNA分子是否与某一种特定的蛋白结合,研究人员根据DNA-Protein实验中DNA Pull down的实验方法进行改进,使其在RNA上实现。 技术步骤如下: (1)设计末端携带T7 RNA Promoter的引物扩增DNA片段; (2)利用T7 RNA polymerase 进行转录,转录过程添加携带生物素的dNTP,使转录本...

GST pull-down is a pull-down assay technique that can be used to confirm existing protein-protein interactions discovered by other techniques or as an initial screening to identify novel protein-protein interactions. By subsequent elution and analysis using western blot or mass spectrometry, a predic...
