7 下拉实验(pull-down Assay) pull-down实验是验证体外蛋白互作的主要实验手段,也是验证无成熟抗体(IP级别)的蛋白互作的方式之一。通过体外表达亲和蛋白-GST/HIS/MBP等(GST、HIS、MBP是最常用的标签),此处以GST(Glutathione S-transferase)为例,将亲和蛋白固化在谷胱甘肽亲和树脂上充当“诱饵蛋白”,将细胞或者组织的...
Pull Down Assay, a technique that involves fixing one protein onto a matrix, allowing for the capture of a binding partner when a cell extract passes through. This captured protein can be retrieved by changing the wash or elution conditions. This method is used to determine the int...

The principle of pull-down assay is affinity purification, which is similar to immunoprecipitation, except that this method uses bait protein, instead of antibody to trap the target protein. In a pull-down assay, a bait protein is tagged and immobilized on beads with affinity ligand specific for...
RheB Pull-Down Activation Assay Kit Cat. # 81201 Introduction A. Background Small GTPases are a super-family of cellular signaling regulators. RheB is a member of the Ras-superfamily GTPases. RheB has been shown to interact with C-Raf, Mammalian target of rapamycin (mTOR), TSC2, Ataxia...
Pull-down assay techniques arein vitromethods for determining the physical interaction between two or more proteins. The principle of pull-down assay is using tags (such as GST, poly-His and biotin) to trap the target protein, which is essentially an affinity purification. ...
In order to verify the results of these pull-down experiments, we have additionally developed two simple validation procedures: An in vitro transcription/translation system coupled with a GEF activity assay and a yeast two-hybrid screen for detection of GEFs. Although the procedures were established...
It is a negative regulator of EGF receptor signaling pathway and synergizes with Notch in mesothorax bristle patterning.Here, we performed a large-scale pull-down assay to screen for Ed direct-interacting proteins in order that we could understand how ed executed its multiple biological functions....
