10 mL BeaverBeads Mag NHS 300 nm for Cell Isolation with Higher Sensitivity​​

1. Description

BeaverBeads™ NHS are superparamagnetic beads with activated groups of N-Hydroxysuccinimide on the surface, which can react with primary amines on desired ligands and bind them covalently with amide linkage to the beads. The ligand can be various molecules including antigen, antibody and other proteins. Compared with the traditional carboxyl, amino magnetic beads, the NHS group of magnetic beads don't need to be activated by EDC/NHS or Glutaraldehyde, simply dissolve the amino-containing bioligand in the coupling buffer at room temperature, then mix with proteins and the NHS magnetic beads for 1-2 hours, the bioligand can be coupled to the magnetic beads. The advantages include easy operation, mild coupling conditions and efficient coupling. The magnetic bead
coupling process must be carried out in a buffer solvent free of any amino. This method can be operated manually or automatically.

2. Features

• Convenient. Direct covalent binding with bioligand, no pre-activation needed
• Efficient. The efficiency of binding with bioligand is up to 90% which is higher than carboxyl magnetic
  beads. Binding capacity is much higher than others'
• Rapid. Complete the bioligand coupling in 1-2 h
• Mild. Binding temperature is RT or 4 ℃ and pH is between 5 and 9
• Stable. Form a stable amide bond in order to prevent ligand shedding
• Good bio-compatibility and low non-specific adsorption

3. Application Case

Use enzyme chemiluminescence method for antibody quantitative detection, the results show that BeaverBeads™ Mag NHS achieve 20% higher sensitivity than the competitive products, showing excellent chemiluminescence performance.

• In-vitro diagnostic
• Immunoassay
• Cell isolation
• Immuno-precipitation
• Protein (antibody) purification
