Virus, Bacteria and Exosome

Exosomes, viruses, and bacteria are small, complex biological particles. Their analysis play critical roles in diagnostics, therapeutics, and research. Isolating them efficiently and extracting nucleic acids with high purity is essential for downstream analysis. 

Our Aurosphere® magnetic beads offer tailored solutions for these applications, with higher magnetization, ensuring fast separation, high recovery, and great reproducibility. 

1. Isolation with Biotinylated Capture

  • Our 200 nm Streptavidin Beads bind efficiently to biotinylated ligands, enabling specific capture of exosomes, viruses, or bacteria from complex media. Their high surface area supports sensitive isolation, even in low-abundance samples.
  • Alternatively, our 800nm Streptavidin Beads can be used for easier handling and when higher magnetization is required.

2. Isolation with Direct Antibody Conjugation

  • Our 200 nm Carboxyl Beads can be covalently functionalized with antibodies or ligands, providing a flexible platform for the selective isolation of exosomes, viruses, or bacteria. Their high surface area supports sensitive isolation, even in low-abundance samples.
  • Alternatively, our 800nm Carboxyl Beads can be used for easier handling and when higher magnetization is required. 

3. DNA/RNA Extraction
Efficient nucleic acid recovery from exosomes, viruses and bacteria is crucial for downstream molecular analysis. Our Silica-Coated Magnetic Beads deliver high binding capacity, reproducible performance, and superior separation efficiency, even in complex media. 

  • 200 nm Silica Beads – High surface area for sensitive recovery, ideal for low-input samples.
  • 800 nm Silica Beads – Faster magnetic separation and easier handling for routine nucleic acid extraction workflows.
