Multiple literature references for GST-Trap
This article provides an overview of scientific publications that reference the ChromoTek GST-Trap superior binding performance for various applications. These include immunoprecipitation (IP), Co-IP of Glutathione S-Transferase (GST)-fusion proteins, and Luminex bead assays of GST-tagged and GFP-tagged proteins. Besides, usages for depletion of GST (glutathione sepharose) after cleavage from recombinant fusion proteins and affinity purification of GST-tagged proteins are possible.

Practical considerations and instructions
Introduction
The ChromoTek Myc-Trap is an affinity resin that consists of Myc-binding protein derived from an Alpaca single domain antibody, also called anti-Myc VHH or “anti-Myc nanobody”, which is coupled to agarose and magnetic agarose beads. The Myc-Trap provides advantages over conventional IgG antibodies when applied in immunoprecipitation (IP) and affinity purification experiments:

ChromoTek Myc-Trap® is an effectiveness optimized tool for immunoprecipitation (IP/Co-IP) and affinity purification of Myc-tagged proteins. Depending on whether you use a single Myc-tag, i.e. 1xMyc (EQKLISEEDL) or a double Myc-tag fused to the protein of interest, i.e. 2xMyc (EQKLISEEDLEQKLISEEDL) you can adjust your experiment. Here, we introduce the epitope of Myc-Trap to discuss its performance for afore mentioned applications.

- Do you have GFP or RFP protein constructs and/or libraries?
- Do you want to screen agonists or antagonists?
- Do you want to save time and start your experiment without method set-up?
Just do it. All you need is the ChromoTek F2H Kit Basic: Transfect the bait and the prey plasmids with the Platform Reagent into the F2H cells. Image and quantify your results already at the next day.

Immunoprecipitation (IP) followed by mass spectrometry (MS) analysis is a powerful method to identify interaction partners of a protein of interest. However, sometimes it can be difficult to obtain reliable results.
Now, the combined use of ChromoTek GFP-Trap for immunoprecipitation and PreOmics iST sample preparation kit is in fact a straight forward, reproducible, and reliable approach to identify protein interaction partners. It even preserves posttranslational modification (PTM) depending protein-protein interactions.
In a recent applications note we have demonstrated how protein interaction partners of PARP1 can be identified: We have immunoprecipitated eGFP-tagged PARP1 protein and its interacting partners using the GFP-Trap_M and subsequently processed the pulldown for MS analysis following the instructions of the iST kit.
PARylation mediates the interaction of PARP1 to several DNA repair proteins. Our results show that those interactions are not disrupted by neither the IP nor the MS sample preparation used herein. Therefore, the streamlined combination of the GFP- Trap and the iST kit’s workflow proves to preserve PTM-mediated protein-protein interactions.

The PreOmics iST kit can also be used with other ChromoTek Nano-Traps.

See the advantages of ChromoTek’s RFP-Trap in ChIP applications as demonstrated by Dr. Caroline Rivers, Laboratory for Integrative Neuroscience & Endocrinology, University of Bristol. In absence of suitable antibodies for an inducible hormone receptor, mCherry has been fused to the N-terminus of the receptor. In order to effectively pull down the mCherry fusion protein DNA complex, ChromoTek's RFP-Trap was used.
