Product Infomation

Product Name	NHS-Activated Agarose Magnetic Beads, 20-45 μm
Catalog Number	MGB-BM-027
Physical Specs	20-45 μm
Description	NHS-activated agarose magnetic beads (Magarose-NHS) allow straightforward and efficient covalent immobilization of proteins onto magnetic bead supports, offering a reliable method for affinity purification of antibodies, antigens, and other biomolecules. The activated agarose beads contain N-hydroxysuccinimide (NHS) functional groups that react with primary amines on proteins or other molecules to form stable amide bonds. Coupling reactions are performed in amine-free buffers at pH 7-9, with efficiency exceeding 80% independent of ligand molecular weight or isoelectric point (pI). Following ligand immobilization, the resulting agarose magnetic beads can be applied in multiple affinity purification workflows.
Applications	Affinity purification of antibodies, antigens or other biological molecules
Particle Size	20-45 μm
Concentration	25% (v/v)
Surface Groups	~50 μmol NHS/mL beads
Shell	6% cross-linked magnetic agarose
Storage Solution	100% isopropyl alcohol
Ligand-binding Capacity	>20 mg IgG/mL beads
Storage	2-8°C
Shelf Life	1 year
