In the fields of life sciences, immunology, cancer research, and regenerative medicine, cell sorting stands as a critical technique for isolating specific cell populations with high purity and viability. Magnetic bead-based cell sorting (MACS) has emerged as a gold standard in this space, speed, simplicity, and compatibility with downstream applications such as cell culture, flow cytometry, and molecular analysis. However, off-the-shelf magnetic beads often fail to meet the unique requirements of specialized experiments—whether due to mismatched surface ligands, suboptimal magnetic responsiveness, or poor biocompatibility. Recognizing this gap, CD Bioparticles, a global leader in advanced biomedical materials, offers a tailored cell sorting magnetic bead design service to empower researchers and biopharmaceutical developers with custom solutions that align perfectly with their specific cell sorting goals.

- Functional Coating Development: Specialized coatings to maintain cell viability, functionality, and downstream compatibility.
Our Services
CD Bioparticles' cell sorting magnetic bead design service follows a customer-centric workflow, combining expertise in materials science, immunology, and process engineering to deliver tailored solutions. Our service portfolio includes the following key components:
Customized Design & Development
We begin with a detailed consultation to understand your specific needs, including:
- Target cell type (e.g., immune cells, stem cells, cancer cells) and corresponding surface markers (e.g., CD3, CD19, CD44, EpCAM)
- Required sorting efficiency (purity >95% as standard, with options for >99% for critical applications)
- Cell viability requirements (e.g., >90% post-sorting for functional assays)
- Experimental conditions (e.g., buffer compatibility, temperature range, incubation time)
3.2 Prototype Fabrication & Validation
Once the design is finalized, we fabricate a small-batch prototype (typically 1–10 mL) for performance testing. Our validation process includes:
- Magnetic Responsiveness: Measured using a vibrating sample magnetometer (VSM) to ensure rapid separation (<5 minutes) under standard magnetic separators.
- Specificity & Purity: Evaluated via flow cytometry, comparing the purity of sorted target cells with unsorted samples.
- Cell Viability: Assessed using trypan blue exclusion or MTT assays to confirm minimal cytotoxicity.
- Stability: Tested under accelerated storage conditions (4°C, 25°C, and 37°C) for 1–3 months to ensure bead functionality and ligand stability.
3.3 Scalable Manufacturing
Our manufacturing facilities are equipped with advanced mixing, coating, and conjugation systems, enabling consistent production of magnetic beads with low batch-to-batch variation. We offer flexible batch sizes, from 100 mL for research projects to 100 L for industrial applications, ensuring cost-effectiveness at every scale.

Our Advantages
High Purity and Yield
Our optimized protocols and high-quality reagents ensure that you get a highly pure and concentrated exosome sample. This is critical for downstream analysis, as it minimizes background noise and allows for more accurate and sensitive results.
Speed and Efficiency
Magnetic bead-based isolation is significantly faster than ultracentrifugation. This efficiency allows for a higher sample throughput, making it ideal for large-scale studies and clinical applications.
Preserved Integrity
The gentle nature of our method ensures that the exosomes remain intact and their biological activity is preserved. This is vital for applications where the function of the exosome or its cargo needs to be studied.
