BcMag™ DVS-Activated Magnetic Beads
BcMag™ DVS-Activated Magnetic Beads are pre-activated, uniform, silica-based superparamagnetic beads coated with high
density DVS (Divinyl Sulfone) functional groups on the surface.  The beads are used to covalently conjugate primary amino,
sulfhydryl, or hydroxyl groups-containing ligands (Fig.1). BcMag™ DVS-Activated  Magnetic Beads are ideal matrix for
immobilizing larger molecules and small peptides because the long-arm (15-atom) hydrophilic linker may reduce steric

Features and Advantages:
  • Pre-activated and ready-to-use
  • Recommended coupling conditions: pH 6-10, 4-25°C, 2–24 h.
  • Stable covalent bond with minimal ligand leakage
  • Produces reusable immunoaffinity matrices
  • Low nonspecific binding
  • Immobilize 1-10 mg protein or 0.1-1 mg peptide/ml beads
  • Applications: Cell sorting, Immunoprecipitation; Purification
for Antibodies, Proteins/Peptides, DNA/RNA
