Empowering CLIA and Enabling Efficient Bioseparation Workflows
In the fields of chemiluminescence immuno‑diagnosis and biosample separation‑purification, magnetic microspheres serve as core solid‑phase carriers. Their particle‑size uniformity, magnetic‑response speed and coupling efficiency directly determine assay sensitivity, reproducibility and manufacturing stability of diagnostic kits. To meet the industry’s urgent demand for high‑performance domestic magnetic‑bead raw materials, Meafound Biotechnology has launched its series of monodisperse polymer‑based magnetic microspheres: Carboxyl Magnetic Microspheres (Mag‑COOH) and Streptavidin Magnetic Microspheres (Mag‑SA). They deliver reliable domestic solutions for in‑vitro diagnostic reagent development and biomolecule capture‑purification.
The bead surface is densely functionalized with abundant carboxyl (‑COOH) groups. Upon standard EDC/NHS activation, stable covalent conjugation can be achieved with amino‑containing biomolecules including antibodies, antigens and nucleic acids. It is the preferred solid‑phase material for antibody‑antigen immobilization and chemiluminescence immunoassay kit development. No complicated pre‑treatment is required. Suitable for the full workflow from reagent R&D to large‑scale manufacturing to support various immunoassay projects.
Manufactured by covalently coupling streptavidin onto carboxyl magnetic microspheres, this product is specially engineered for chemiluminescence detection platforms and biotin‑streptavidin signal‑amplification systems. Leveraging the high‑specificity binding between biotin and streptavidin, the beads efficiently capture diverse biotin‑labelled target molecules, greatly boosting assay signals and minimizing non‑specific background. Well‑suited for high‑throughput tests on fully‑automated chemiluminescence instruments.
Highly Uniform Particle Size for Reliable Batch‑to‑batch Consistency
Fabricated as monodisperse microspheres via high‑molecular‑weight polymer matrices with ultra‑narrow particle‑size distribution. It reduces batch‑to‑batch variations and guarantees consistent test results, complying with strict quality‑control requirements for large‑scale IVD production.
Fast Magnetic Response with Excellent Re‑dispersibility
Achieve rapid magnetic enrichment under magnetic fields. After magnetic separation, beads can be readily re‑suspended without aggregation or sedimentation. It simplifies manual handling and adapts to high‑speed operation of automated instruments.
Versatile Surface Modifications for Diverse Conjugation Requirements
Two mainstream surface‑functionalized options (carboxyl and streptavidin) support two major technical routes: direct covalent coating and indirect biotin‑mediated capture, matching different reagent‑development strategies.
Broad Platform Compatibility for Mainstream CLIA Instruments
Fully validated to be compatible with most commercially‑available chemiluminescence immunoassay platforms. Diagnostic manufacturers can implement raw‑material replacement and methodological validation efficiently to shorten time‑to‑market.
