Product Information

Kit for IP/ Co-IP of mNeonGreen tagged proteins and sample preparation for mass spectrometry (MS)

• Description: The iST mNeonGreen-Trap Kit enables researchers to process mNeonGreen-tagged proteins and their interacting partners for MS analysis by including the mNeonGreen-Trap for immunoprecipitation/Co-IP of mNeonGreen-tagged 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 mNeonGreen-fusion proteins & interacting partners by MS

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

  • Superior processing of IP samples into clean peptide mixtures

  • Intuitive protocol for reproducible results

• Applications: IP, MS
• Specificity/Target: mNeonGreen
• Binding capacity: 30 μg of recombinant mNeonGreen 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 K_D of 2 nM
• Compatibility with mass spectrometry: The mNeonGreen-Trap is optimized for on-bead digestion.
• Storage Buffer: 20% EtOH
• Storage Condition: Kit is shipped at ambient temperature. Upon receipt store mNeonGreen-Trap at 4°C and Digest at -20°C
