Beadstar-mPlex®Streptavidin Magnetic Fluorescence Encoded Microspheres - Product Description

Beadstar Biotechnology specializes in the development and production of high-performance magnetic fluorescence encoded microspheres under the Beadstar-mPlex® series. Engineered for superior performance in multiplex immunoassays and nucleic acid detection, our microspheres are compatible with major flow cytometry platforms (CBA system) .

• • Core Features & Key Advantages:

  • Exceptionally Low Background Noise: Utilizing advanced low-absorption technology to significantly reduce non-specific binding. Empirical data shows that reagents developed with this product can achieve a detection fluorescence background as low as 5% of that observed with leading imported counterparts, establishing a foundation for highly sensitive detection.

  • Highly Efficient Biotin Coupling: Leverages the efficient, rapid, and stable interaction between streptavidin and biotin, making the immobilization of capture antibodies extremely simple with straightforward and robust procedures, thereby enhancing batch-to-b consistency.

  • Significant Antibody Cost Savings: Compared to traditional covalent coupling protocols using carboxyl microspheres, the biotin-streptavidin bridge method can save up to 50% in total antibody consumption, with a dramatic reduction of up to 90% in the usage of the critical cost driver—capture antibodies—offering substantial economic benefits.

  • High Encoding Capacity & Stability: Inherits the mature encoding technology from the carboxyl microspheres, supporting highly multiplexed assays from tens to over a hundred targets, ensuring stable and accurate code signal integrity in complex biological samples.

  • Strong Magnetic Responsiveness: Incorporates a high-content iron oxide core, enabling rapid magnetic separation within 30-60 seconds, significantly streamlining assay workflows.

Applications:

• Multiplex Protein Detection (e.g., Cytokine Panels)

• Nucleic Acid Detection (including assays requiring heat denaturation)

• IVD Reagent Development

• Immunoassay Research & Development
