What mass spectrometry techniques are commonly used for pull down MS
Pull Down Mass Spectrometry is a common mass spectrometry technique mainly using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pull Down Mass Spectrometry is a technique used to analyze protein interactions. This method, through 'Pull Down' experiments combined with mass spectrometry, can accurately identify and quantify protein interactions.
In a Pull Down experiment, the target protein is first linked with a specific binding protein or small molecule, and then, through a series of washing steps, non-specifically bound proteins are removed. Finally, what remains are the proteins that specifically bind to the target protein.
These protein complexes are then further analyzed to identify the bound proteins. LC-MS/MS plays a crucial role in this process. By performing mass spectrometry analysis on the protein complexes, it can accurately identify the proteins bound to the target protein.
