Product Description

Agarose NHS Magbeads Preactivated N - Hydroxy Succinimide Nanoparticle​ 30 - 150 μm, 20% (v/v)


1, Description:

BeaverBeads ™ Mag NHS and BeaverBeads ™ Magrose NHS are spherical beads modified with NHS groups capable of forming stable peptide bonds with proteins and other molecules with primary amine groups for affinity purification or assay detection of antibodies, antigens and other biomolecules. Compared with the traditional beads with carboxyl or amino groups, the beads with surface containing NHS group do not need to be activated by EDC / NHS or glutaraldehyde in advance. Simply by dissolving the ligand containing the primary amino acid in the coupling buffer (mix the protein solution with Mag NHS beads at room temperature for 1 ~ 2h), the ligands will be attached on the beads.

  • 1. Simple, without activation, can be directly covalently coupled with the biological ligand;

  • 2. Efficient, bio-ligand coupling efficiency of up to 90% or more, much higher than the carboxyl beads, while the ligand with a higher binding capacity;

  • 3. Fast, 1 ~ 2h to complete the bio-ligand coupling;

  • 4. Mild, room temperature or 4 ℃ coupling, coupling system pH 5 ~ 9;

  • 5. Stable, the formation of a stable amide bond, to prevent the ligand off.

  • 6. Good biocompatibility, reduced nonspecific adsorption.
