Streamline affinity purification with CaptureSelect products

Thermo Scientific CaptureSelect technology enables the purification of antibodies, antibody fragments and proteins with proven affinity solutions.  These products enable increased purity and yield and are designed to simplify research workflows and reduced time and cost in biopharmaceutical drug development.


  Bioprocess products: Unique products for the highly efficient direct capture purification of various biomolecules such as antibodies and antibody fragments, fusion proteins (Fc and albumin) and biosimilar hormones. Paired leakage assays offer additional tools for process development or for routine quality control processes.

Antibody derived therapeutics      Biosimilars and recombinant proteins 
Viral vectors ad vaccines
  Custom ligand development: Service for the development of product and process specific affinity solutions.

R&D scale purification: Collection of ready-to-use resins suitable for small scale purification

  • Antibody Purification: purify virtually any antibody format from any species using our diverse product portfolio
  • Protein Purification: one-step solution for the purification of non-antibody biopharmaceuticals
  • C-tag: smallest affinity tag system (4 amino acid recognition) available on the market, offering high selectivity, affinity, and a variety of elution conditions

Quantitation and detection: Companion products for further characterization and quantitation of biomolecules

  • HPLC columns: Prepacked Thermo Scientific POROS CaptureSelect Affinity Columns for rapid quantitation of immunoglobulins, fusion proteins, Fabs, and bispecific antibodies
  • Ligand Conjugates: Biotinylated CaptureSelect ligands for use in analytical assays, including Western Blots and label-free systems
  Plasma sample preparation: Single-step, single-use depletion of highly abundant proteins from human serum and plasma, 99% protein removal before 2D gel or Mass spec analysis.
