V5-Trap Magnetic Particles M-270

Description

The ChromoTek V5-Trap® Magnetic Particles M-270 consists of an anti-V5-tag Nanobody (VHH), which is covalently bound to Magnetic Particles M-270. V5-Trap Magnetic Particles M-270 is used to immunoprecipitate V5-tagged fusion proteins from cell extracts of various organisms like mammals, plants, bacteria, yeast, insects etc

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

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

Affinity
Dissociation constant KD of 40 nM

Wash buffer compatibility
2 % Nonidet P40 Substitute, 2 % Triton X-100, 150 mM NaCl, 10 mM TCEP, 10 mM DTT,  50 mM Urea

Specificity
V5-tag sequence motif GKPIPNPLLGLDST

Binding capacity
10 µL slurry bind ~ 0,25-0,5 µg of recombinant V5-tagged protein ~30 kDa

Coupled Nanobody/ VHH
recombinant, monoclonal anti-V5-tag single domain antibody (sdAb) fragment

Bead properties
Bead size: ~ 2,8 µm
Storage buffer: 1x PBS, Preservative: 0.09 % sodium azide

Elution
- V5-peptide. For details see below.
- 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 V5-Trap is optimized for on-bead digestion (see protocol).

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.
