Product Information
Kit for IP and Co-IP of RFP- and mCherry fusion proteins & sample preparation for mass spectrometry (MS)
| Description | The iST RFP-Trap® Kit for processing RFP-fusion proteins and their interacting partners for mass spectrometry analysis: The kit includes the RFP-Trap for IP/Co-IP of RFP-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 RFP-fusion proteins & interacting partners by MS • Identification of even low abundant RFP-fusion proteins • Superior processing of IP samples into clean peptide mixtures • Intuitive protocol for reproducible results |
| Applications | IP, MS |
| Specificity/Target | mRFP, mCherry, mRFPruby, mPlum, tagRFP, mKate2, mOrange, PA-mCherry, mScarlet For the complete list, please click here: Fluorescent protein specificity table |
| Binding capacity | 22.5 μg of recombinant RFP per 25 μL bead slurry |
| Conjugate | Agarose beads; bead size: ~ 90 µm (cross-linked 4 % agarose beads) |
| Type | Nanobody |
| Class | Recombinant |
| Host | Alpaca |
| Affinity (KD) | Dissociation constant KD of 5 nM |
