Sera-Mag™ Carboxylate-Modified Magnetic Beads & SpeedBeads have free carboxyl groups on the surface for convenient covalent coupling of target molecules (proteins, peptides, and amine-modified ligands) via primary amines (NH2). 

  • Wide application range: Carboxylic groups on the surface form covalent amide bonds with proteins, peptides or amine-modified ligands for use in many downstream applications including protein purification, DNA sample preparation and clean-up, protenomicsand immunoassays.
  • Convenient one-step or two-step coupling: Carbodiimide chemistry allows rapid formation of stable bonds to minimize ligand leaching.
  • Fast magnetic separation: Available in original Sera-Mag™ format or Sera-Mag™ SpeedBeads version for faster magnetic response and shorter assay times in clinical diagnostic tests.
  • High performance: Excellent sensitivity and low nonspecific binding for greater accuracy; different levels of hydrophobicity/hydrophilicity available.
