Product Information

Kit for IP/ Co-IP of GFP-fusion proteins & sample preparation for mass spectrometry (MS)

• Description: The iST GFP-Trap® Kit enables researchers to process GFP-fusion proteins and their interacting partners for Mass Spectrometry analysis by including the ChromoTek GFP-Trap for immunoprecipitation/Co-IP of GFP-fusion proteins and the PreOmics iST buffers and cartridges required for bottom-up proteomic sample preparation. This robust method yields purified peptides while dramatically reducing contamination and sample loss. Each kit accommodates up to eight samples and includes pull-down reagent for controls:

  • Reliable dentification of GFP-fusion proteins & interacting partners by MS

  • Identification of even low abundant/ low expressed GFP-fusion proteins

  • Superior processing of IP samples into clean peptide mixtures

  • Intuitive protocol for reproducible results

• Applications: IP, MS
• Specificity/Target: AcGFP, Clover, eGFP, Emerald, GFP, GFP5, GFP Envy, GFP S65T, mGFP, mPhluorin, PA-GFP, Superfolder GFP, TagGFP, TagGFP2, monomeric eGFP A206K, CFP, YFP, Citrine, eCitrine, eYFP, Venus, Ypet, BFP ; For the complete list, please click here: Fluorescent protein specificity table
• Binding capacity: 25-30 µg of recombinant GFP per 25 µL bead slurry
• Conjugate: Agarose beads; bead size: ~ 90 µm (cross-linked 4 % agarose beads)
• Type: Nanobody
