Thermo Fisher Scientific Pierce GST Tag Protein Interaction Pull-Down Kits contains the necessary components to capture and purify proteins that interact with GST-tagged fusion proteins.

Features of GST Tag Protein Interaction Pull-Down Kit:

  • GST pull-down (Product No. 21516)—gently purifies protein interactors of any GST-tagged fusion protein without denaturing
  • Complete kits—provide all components and detailed protocol for purifying protein:protein interactions
  • No special equipment needed—use common laboratory equipment and reagents (e.g., microcentrifuge)
  • Convenient—microcentrifuge spin columns facilitate simple and efficient manipulation of agarose beads, including simple processing of multiple samples
  • Flexible—instructions include protocols for use with bait and prey proteins from many different sources
  • Binding—Binds approx. 8 mg of GST-tagged fusion protein per mL of resin

Applications:

  • Discover a new protein:protein interaction from a cell lysate
  • Confirm a putative interaction from a cell lysate or with a previously purified protein
  • Extract protein:protein interaction information from in vitro transcription/translation lysates

You provide the tagged fusion protein as the 'bait' and the cells expressing the putative protein interaction target ('prey'), and the Pull-Down Kits provide everything else: cell lysis buffer, microcentrifuge spin columns, tag-specific affinity resin (agarose beads) and optimized buffers and protocol. The Pull-Down Kits are designed to teach the method to first-time users and to increase ease-of-use, convenience and reproducibility for experienced researchers.

For Research Use Only. Not for use in diagnostic procedures.

Pull-down is a small-scale affinity purification technique similar to immunoprecipitation (IP), except that the antibody function of is replaced by some other affinity system. In this case, the affinity system is a GST-tagged protein that can be captured by glutathione agarose beads. The fusion-tagged protein acts as the bait to capture a putative binding partner (i.e., the prey). In a typical pull-down assay, the immobilized bait protein is incubated with a cell lysate. After the prescribed washing steps, the interactors are selectively eluted for analysis in-gel or by Western blot.
