High Performance Magnetic Beads for Immunoassays

publication date: Jan 9, 2024
author/source: AMSBIO



AMSBIO has expanded its range of high-performance magnetic beads for use as detection labels in magnetic immunoassays or as a solid support phase in immunoassays.

MagSi-STA beads are magnetic silica particles with high quality streptavidin covalently attached to the bead surface. Available in different mean sizes, streptavidin coupling chemistries and binding capacities, these industry-leading MagSi-STA beads offer an optimized solution for many in vitro diagnostic applications, including immunoassays.

To streamline the process of selecting the most suitable streptavidin beads for specific applications, AMSBIO has launched the MagSi-STA Trial kit. This kit is especially useful when required specifications for magnetic beads are not known. Designed for evaluation purposes during trial phase of developing new assays or bead replacement in existing assays, the Trial kit includes 1ml of each of the eight different MagSi-STA products to enable researchers find the most appropriate beads for their specific application quickly.

MagSi-STA beads are based on a silica matrix, which produces lower background chemiluminescence and UV/VIS signals compared to alternative substrates inherent luminescent properties like polystyrene, thereby enhancing assay sensitivity and dynamic range. As a consequence, MagSi-STA beads are suitable for almost any assay, regardless of read out method used. The silica matrix also ensures product stability over a wide pH range and at high ionic strength conditions.

AMSBIO supplies a unique expansive range of magnetic silica beads for biological applications. These magnetic beads range in size from 150nm to 5μm and can have a wide range of surface properties, functional groups, and magnetic properties. MagSi beads are specifically designed for the separation, concentration and purification of biomolecules and specific cells or cell compartments.
