Overview

The protein sorting magnetic bead service by CD Bioparticles is built on the core principle of specific affinity interaction between magnetic beads and target proteins. Our service utilizes superparamagnetic nanoparticles (with diameters ranging from 50 nm to 5 μm) as the core matrix, whose surfaces are modified with high-affinity ligands (e.g., monoclonal antibodies, Protein A/G, Ni-NTA, biotin-streptavidin, or custom ligands). These ligands enable highly specific binding to target proteins based on their structural features, tags, or biological properties.

Our Services

CD Bioparticles offers a comprehensive suite of services to support researchers in their protein sorting applications, from standard products to fully customized solutions.

Ready-to-Use Magnetic Beads

We maintain an extensive inventory of pre-conjugated magnetic beads with common protein binding ligands for immediate shipment. These include:

  • Protein A/G magnetic beads: Ideal for simultaneous isolation of IgA and IgG proteins through a single manual or automated magnetic separation step, significantly reducing processing time compared to sequential Protein A and Protein G purification.
  • Antibody-conjugated beads: We offer beads pre-conjugated with common antibodies for frequently targeted proteins, providing researchers with ready-made tools for specific immunoprecipitation applications.
  • Streptavidin/biotin system beads: Our ready-to-use streptavidin magnetic beads facilitate quick setup of biotin-based capture systems without the need for conjugation procedures.

Custom Conjugation Services

Our custom conjugation service represents the core of our specialized offerings. We understand that researchers often work with unique targets or require specific binding characteristics that standard products cannot address. Our custom service includes:

  • Ligand coupling: We conjugate customer-provided antibodies, proteins, peptides, or other capture molecules onto our optimized magnetic bead platforms. This service is particularly valuable for researchers working with rare antibodies or proprietary binding molecules.
  • Surface chemistry optimization: We tailor the surface chemistry of our beads to match the specific requirements of different applications, optimizing parameters such as hydrophobicity/hydrophilicity balance, spacer arm length, and functional group density to maximize binding efficiency and minimize non-specific interactions.
  • Scale flexibility: Our services accommodate projects ranging from small-scale pilot studies requiring milligram quantities to large-scale production needs with gram-scale batches, ensuring consistent performance across different production scales.

Applications of Our Protein Sorting Magnetic Beads

The versatility of our magnetic bead technology enables applications across diverse research areas:

  • Antibody Purification and Immunoprecipitation

Our Protein A/G magnetic beads excel in antibody purification from various sources including serum, cell culture supernatant, and ascites fluid. The magnetic separation format significantly reduces processing time compared to column-based methods while maintaining high purity and yield. For immunoprecipitation applications, the beads enable efficient target protein pull-down with minimal non-specific binding, resulting in cleaner results and reduced background in downstream analyses.

  • Protein-Protein Interaction Studies

Understanding protein interactions is fundamental to deciphering cellular signaling pathways. Our magnetic beads provide an efficient platform for co-immunoprecipitation (Co-IP) experiments, enabling researchers to isolate native protein complexes under gentle conditions that preserve these interactions. The magnetic separation process subjects the analytes to minimal mechanical stress compared to centrifugation-based methods, helping maintain the integrity of delicate complexes
