The magnetic bead adapter coupling service is the connection between the high selectivity of adapter and the good separability of magnetic bead. The product formed by the combination of the two can be widely used in targeted detection, purification and analysis. CD Bioarticles is dedicated to providing customized conjugation service to link the two technologies, to meet the dynamic needs of researchers and industries. We aim to support the development of new efficient and reusable tools for biomedical diagnosis to environmental monitoring, ensuring high accuracy, speed and reliability for every project.

Overview of Magnetic Bead Enzyme Conjugation
Magnetic beads can rapidly separate target complexes using an external magnetic field, with the advantages of large binding surface area, and excellent biocompatibility. Aptamer bound to magnetic beads will form magnetic bead adapter conjugate which allows for the aptamers to target specific analytes such as proteins, cells or small molecules, while magnetic beads can rapidly separate complexes bound to aptamers away from complex samples. The synergy of magnetic beads and aptamers simplifies workflow, reduces background interference and increases detection sensitivity. CD Bioparticles are experienced in the application of cutting-edge coupling chemistry and our experience with adapter biology and magnetic materials science to manufacture conjugates with excellent binding efficiency, stability and function.
Applications
Magnetic bead enzyme coupling has diverse applications in various fields, such as:
Biomedical Diagnostics
Magnetic bead adapter conjugates can sensitively detect disease biomarkers (for example, cancer antigens, infectious agents or cardiovascular markers) in blood, serum or urine. Aptamer bound to magnetic beads can also be used to enrich circulating tumor cells (CTCs) from patient samples to help with the early diagnosis and prognosis of cancer.
Biomolecular Purification
This conjugate simplifies the isolation of specific proteins, nucleic acids or exosomes from cell lysates or biological fluids. The high specificity of the adapter ensures high purity, while the magnetic separation method avoids the need for centrifugation or chromatography to save time and cost.
Environmental Monitoring
Detection of pollutants, toxins or heavy metals in water, soil or air samples can also be done. The binding ligands on the target pollutants can be bound by the magnetic beads which will allow the complex to be concentrated and detected rapidly even at trace level.
Our Services
CD Bioparticles has a complete range of magnetic bead adapter coupling services, all of which can be customized based on your needs:
Customized coupling design
We can couple different aptamers (DNA, RNA, or peptide aptamers) to different magnetic beads (iron oxide beads, polymer coated beads, or functionalized beads with carboxyl, amino, thiol, or biotin groups). We will optimize adapter loading density, coupling efficiency, and bead size according to the needs of the application.
Adapter modification and labeling
If needed, we can add reactive groups (amines, thiols, etc.) or markers (fluorescent dyes, biotin, etc.) to the adapter to improve coupling or to enable multimodal detection.
Combining efficiency and specificity testing
We will use ELISA, fluorescence polarization, or surface plasmon resonance (SPR) to confirm that the conjugate binds to the target with high affinity and specificity. This step is critical to ensure the binding performance of the conjugate.
Scalable production
Whether it is for small-scale research (micrograms) or large-scale industrial production (grams), we can scale up production according to requirements and maintain strict quality control. Our process is flexible and can meet both academic and business needs.
Quality assurance
We perform a series of tests for each batch of products, including:
- Binding efficiency (UV Vis spectroscopy or qPCR)
- Binding affinity and specificity for the target
- Magnetic responsiveness and particle size distribution
- Stability under storage and analysis conditions

1. How do you ensure the aptamer retains its binding specificity after conjugation?
We use gentle conjugation chemistries that avoid modifying the aptamer’s target-binding region. Post-conjugation, we test binding specificity using target and non-target molecules to confirm no loss of selectivity.
2. How do you ensure the stability and activity of the conjugated aptamers?
We employ optimized conjugation protocols and utilize appropriate blocking agents to minimize aptamer denaturation and maintain binding activity. Our rigorous quality control includes binding assays to confirm the functional activity of the conjugated aptamers.
3. How do you ensure that the adapter maintains its binding specificity after binding?
We use mild conjugated chemicals so that the target binding region of the adapter is not modified. Then we use both target and non-target molecules to test the binding specificity after binding to ensure that there is no loss of selectivity.
4. Can you design a customized adapter for me according to my goal?
Although our primary service is integration, we are also in touch with professional adapter screening companies, which provides us with an end-to-end solution for customers, including adapter selection through SELEX (Systematic Evolution of Exponential Enrichment Ligands).
