mNeonGreen-Trap Magnetic Agarose

Description
The ChromoTek mNeonGreen-Trap Magnetic Agarose is an affinity resin for immunoprecipitation of mNeonGreen-fusion proteins.
It consists of a mNeonGreen Nanobody/ VHH coupled to magnetic agarose beads.

Specificity
mNeonGreen, Branchiostoma lanceolatum

Applications
Immunoprecipitation/ Co-IP
Mass spectrometry
On-bead enzyme assays
ChIP/ RIP analysis

Affinity
Dissociation constant KD of 2 nM

Wash buffer compatibility
4 M urea, 2 M NaCl, 10 mM DTT, 2 % Nonidet P40 Substitute, 1 % Triton X-100, 0.2 % SDS

Specificity
mNeonGreen, Branchiostoma lanceolatum

Binding capacity
10 µL slurry bind more than 12 µg of recombinant mNeonGreen

Coupled Nanobody/ VHH
recombinant, monoclonal anti-mNeonGreen single domain antibody (sdAb) fragment

Bead properties
Bead size: ~ 40 µm
Storage buffer: 20 % EtOH

Elution
- SDS sample buffer
- 0.2 M glycine pH 2.5
Please consider whether elution is really needed. We recommend on-bead assays like on-bead digestion for MS analysis.

Compatibility with mass spectrometry
The mNeonGreen-Trap is optimized for on-bead digestion. Complete tryptic digest results in 5-6 peptides.

Storage instructions
Shipped at ambient temperature. Upon receipt store at 4°C; stable for one year.

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 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?

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.

Benefits

  • Superior pulldown of mNeonGreen-fusion proteins
  • No heavy & light chains in your downstream application
  • Strong binding even under harsh washing conditions
  • Short incubation time of about 60 minutes

mNeonGreen-Trap Magnetic Agarose Kit

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