BcMag™ NHS-Activated Magnetic Beads are uniform, silica-based superparamagnetic beads coated with high density NHS (N-
hydroxyl succinimide) functional groups on the surface.  The beads are used to specifically conjugate primary Amine-containing
ligands (Fig.1), so other active groups in the ligand do not need to be protected prior to coupling. Coupling is fast (15–30 min at
room temp pH 6.5–9, 4 hours at 4 °C).  BcMag™ NHS-activated Magnetic Beads are most suitable for conjugation of  large
proteins. BcMagTM Long-arm (17 atome) NHS-activated Magnetic Beads are recommended for conjugation of small peptides
because the long-arm (21-atom) hydrophilic linker may reduce steric hindrance.

Features and Advantages:

• Pre-activated and ready-to-use
• Quick coupling in neutral pH (6.5–9) 4 to 25°C.
• 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
