High-performance magnetic beads for immunoassay optimisation

MagSi-STA magnetic beads

AMSBIO has expanded its portfolio to include MagSi-STA beads, high-performance magnetic beads suitable for use as detection labels in magnetic immunoassays or as a solid support phase in immunoassays. These beads feature a silica matrix with covalently attached streptavidin, offering various sizes, chemistries, and binding capacities to optimise in vitro diagnostic applications.

To simplify bead selection for specific applications, AMSBIO has launched the MagSi-STA Trial kit. This kit is particularly valuable during the trial phase of assay development, providing 1ml samples of each of the eight MagSi-STA products for quick evaluation and selection based on application requirements.

MagSi-STA beads, based on a silica matrix, offer advantages such as lower background chemiluminescence and UV/VIS signals compared to alternative substrates like polystyrene. This characteristic enhances assay sensitivity and dynamic range, making MagSi-STA beads suitable for various assays, regardless of the readout method. The silica matrix ensures product stability across a wide pH range and under high ionic strength conditions.

AMSBIO's extensive range of magnetic silica beads, including MagSi beads ranging from 150nm to 5μm, provides diverse options for biological applications. These beads are designed for the separation, concentration, and purification of biomolecules, specific cells, or cell compartments.
