The ChromoTek Myc-Trap® Magnetic Agarose is an affinity resin for immunoprecipitation of Myc-fusion proteins.
It consists of a Myc Nanobody/VHH coupled to magnetic agarose beads.
Myc-tag sequence motif EQKLISEEDL at the N-terminus, C-terminus, or internal site of the fusion protein.
Endogenous c-myc is NOT bound.

Please consider whether elution is really needed. We recommend on-bead assays like on-bead digestion for MS analysis.
Compatibility with mass spectrometry
The Myc-Trap is optimized for on-bead digestion. Complete tryptic digest results in 6-7 peptides.

Does the Myc-Trap bind endogenous c-Myc protein?
We could not detect binding of endogenous c-Myc protein to the Myc-Trap. Some epitope residues that have shown to be crucial for binding to the Myc-Trap are buried in the three-dimensional structure of the c-Myc protein. Hence, under native conditions, c-Myc protein is not a suitable binding partner for the Myc-Trap.
How can I gently elute native Myc-tagged protein from the Myc-Trap in its native state?
You can elute your Myc-fusion competitively with 1x or 2x Myc-peptide. Alternatively, you can use 8 M Urea or 0.2 M glycine pH 2.5 at room temperature.
Should I use 1x Myc- or 2x Myc-peptide for elution of the Myc-Trap?
It is likely that the Myc-Trap binds several motifs of a double Myc-tag. Hence, elution of a Myc-tagged fusion protein is more efficient with the 2x Myc-peptide. In addition, the term "Myc-tag" can refer to a single or double Myc-tag. To be on the safe side in this case as well, we would recommend to elute with the 2x Myc-peptide.
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.
- No heavy & light antibody chains
- Pull-down of Myc-tagged proteins
- Elution of native proteins
- One step immunoprecipitation
1x Myc-Tag or 2x Myc-Tag: Binding and Elution
Both, 1x Myc- and 2x Myc-tagged Protein of Interest (POI) can be used for all kind of IPs, Co-IPs, and affinity purification. To further optimize your experiment:
- Use 1x Myc-tagged POI if you like to effectively or gently elute your protein of interest from Myc-Trap in native conditions.
- Use 2x Myc-tagged POI if you like to effectively pull-down/bind low expressed/abundant proteins. For downstream assays we recommend on-bead applications like on-bead digestion and on-bead assays.
