TurboGFP-Trap Magnetic Agarose is an affinity reagent for immunoprecipitation (IP) of TurboGFP fusion proteins.
It consists of an anti-TurboGFP VHH/ Nanobody that is coupled to magnetic agarose beads.
TurboGFP derived from CopGFP from the copepod Pontellina plumata.
The TurboGFP-Trap does not bind to jellyfish GFP and derivatives, see: Fluorescent protein specificity table

Please consider whether elution is really needed. We recommend on-bead assays like on-bead digestion for MS analysis.
Compatibility with mass spectrometry
The TurboGFP-Trap is optimized for on-bead digestion. Complete tryptic digest results in 5-6 peptides.
Shipped at ambient temperature. Upon receipt store at 4°C. Stable for one year.
Does the GFP-Trap bind TurboGFP?
No, the GFP-Trap doesn't bind TurboGFP. TurboGFP is a green fluorescent protein derived from CopGFP of the copepod Pontellina plumata whereas GFP has been originally isolated from jellyfish Aequorea Victoria. Turbo-GFP shares only ~20 % sequence identity with the commonly used GFP variants.
Should I use an N-terminal or C-terminal fusion tag?
Both the N-terminal or C-terminal fusion tag work well with the traps.
How can I avoid unspecific protein interactions binding to the trap?
How can I elute bound proteins from a trap in their native state?
You can elute your fusion protein of interest with 0.2 M glycine pH 2.5 at room temperature. Pipette the beads up and down for 60-120 seconds and repeat this step. Ensure to neutralize your supernatant immediately afterwards by adding 1 M Tris base pH 10.4.
How many mammalian cells are required for an immunoprecipitation reaction?
For one immunoprecipitation reaction, we recommend using ~10^6 - 10^7 mammalian cells. The yield is also dependent on the expression level of your protein of interest and the interaction partners.
How much cell extract should I use for an immunoprecipitation reaction?
For other type of cells than mammalian cells, we recommend using 0.5 - 1.0 mg of cell extract.
Do I need to elute bound proteins from the beads for mass spectrometry analysis?
Do I need to elute my protein of interest from the beads for enzymatic assays?
What is the amount of trap slurry I need for one immunoprecipitation reaction?
25 µL slurry are sufficient for one pull-down reaction as the affinity of the traps is very high.
- Low background
- NO heavy and light antibody chain contamination
- High binding affinity
- Harsh washing conditions
