TEV HALO Magnetic Nanoparticles

Tobacco Etch Virus protease (TEVp)-labelled superparamagnetic nanoparticles for optimal recovery and reuse in protein preparation applications.


  • Simplifies protein preparations by abolishing the need to remove TEVp via column chromatography
  • Beads can be reused for multiple protease reactions
  • Significantly reduces downstream protease contamination
  • Suitable for cleavage of affinity tags, identification of TEV sites in proteins, and activation/inactivation of engineered proteins
  • Active in multiple buffer systems (e.g., PBS; TBS; Imidazole)

Proteases with highly specific activities have applications in the purification and downstream processing of overexpressed proteins, including the cleavage of affinity tags and solubility promoting partners such as GST and MBP. However, proteases can be challenging to express and purify, and commercially sourced proteases such as TEV and 3C can be prohibitively costly.

Concentration: 5 mg/mL
Mean Diameter: 60 um
Comments: End-users who obtain this product will need a magnet for bead separation
Storage: +4C (do not freeze)
Shipped: Cold packs

From the laboratory of Robert M. Hughes, PhD, East Carolina University.

Suggested reaction conditions: Utilize 50-100 μL bead suspension per 250 μL-1 mL reaction; conduct reactions at room temperature to 30C for 6 h to overnight on rotator. Collect beads on magnet for 5 min prior to recovery of supernatant. Beads are active for > 1 month if stored at 4C. Beads can be reused for multiple protease reactions.

Tip: Add DTT or β-ME to a final concentration of 10 mM for optimal substrate proteolysis.
