The Pierce™ GST Interaction Pull-Down Kit contains the necessary components to capture and purify proteins that interact with GST-tagged fusion proteins.

• Complete kits provide all components and detailed protocols for purifying protein:protein interactions
• No special equipment needed – use common laboratory equipment and reagents
• Microcentrifuge spin columns facilitate simple and efficient manipulation of agarose beads, including simple processing of multiple samples
• Instructions include protocols for use with bait and prey proteins expressed from a variety of sample types
• Cobalt chelate resin is more specific for histidine-tagged fusion proteins than nickel resins, resulting in less non-specific binding
• Binds 10 to 25 mg of histidine-tagged fusion protein per ml of resin

Applications include discovering a new protein:protein interaction from a cell lysate; confirming a putative interaction from a cell lysate or with a previously purified protein; extracting protein:protein interaction information from in vitro transcription/translation lysates.
