V5-Trap Magnetic Agarose

The ChromoTek V5-TrapTM Magnetic Agarose is an affinity resin for immunoprecipitation of V5-tagged proteins.
It consists of a anti V5 Nanobody/VHH coupled to magnetic agarose beads.

V5-tag amino acid sequence GKPIPNPLLGLDST at the N-terminus, C-terminus, or internal site of the fusion protein.

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?

For preclearing of your sample we recommend to use our binding controls (bab-20 or bmab-20).

Please find more information in our Troubleshooting guide

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?

No, you can directly conduct an on-bead digestion after immunoprecipitation. This procedure allows faster and more efficient sample preparation and a potential higher yield.

Protocol on-bead digestion

Do I need to elute my protein of interest from the beads for enzymatic assays?

No, you can directly perform your enzymatic assay on the beads if the active center is not blocked.

Please find more information in our application note "enzymatic activity assay"

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.


  • No heavy & light antibody chains
  • Pull-down of V5-tagged proteins
  • Harsh washing conditions
  • Elution of native proteins
  • One step immunoprecipitation
  • Reproducible results

V5-Trap Magnetic Agarose Kit

The V5-Trap Magnetic Agarose is also available in a kit, including:

  • V5-Trap Magnetic Agarose
  • Lysis*, dilution and wash buffers

*The lysis buffer provided is suitable for mammalian cells. For other cell types use another suitable lysis buffer.

Binding Control for Magnetic Agarose Beads


The V5-peptide may be used to elute native and functional V5 fusion proteins:

Which V5-Trap should I use?

  • V5-Trap Agarose, when lowest background and high binding capacity IP is needed. 
  • V5-Trap Magnetic Agarose, when magnetic separation and high binding capacity IP is needed.
  • V5-Trap Magnetic Particles M-270, when very large proteins/complexes are investigated, and magnetic separation is needed for IP.
