Silica-coated uniform superparamagnetic beads, MagneZoom, with an aldehyde surface group. It is widely used to covalently couple ligands containing primary and secondary amino groups. This coupling method will provide an extremely stable linkage between the ligand and the matrix. Size: 2-5µm …

Silica-coated uniform super paramagnetic beads with surface carboxyl group. Proteins and nucleic acids can be covalently bound to these beads with the retention of biological activity. Size: 5-10µm. COOH terminated Binding: up to 20mg/ml. pH stability: 4-9 Supplied as 25mg/ml…

bioSilica Beads Non-porous silica beads are useful in molecular biology and immunoassays. Diameters are 0.3-5.0 µm, a density of 1.96g/cm 3 , a refractive index (589nm) of about 1.37. Silica beads have high temperature stability. Also, because hydrophilic silica does not absorb proteins,…
