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 |
