Custom Antibody Development Services

Your Antibody, Our Expertise

Generation of new custom antibodies can be a long, frustrating, and potentially expensive process. The probability of success depends on multiple factors including intended use, biological knowledge of the target’s structure and function, appropriate immunogen design, animal model and clonality chosen, immunization strategy, optimized screening methods, efficient purification, and reliable QC.

Leverage the experience and expertise of our custom antibody development scientists for your project. Our consultative, stage-gated approach mitigates risk, saves time and increases the probability of your project successfully moving forward.

  • PerCP, FITC, PE, APC

Antibody Characterization Services

Reproducibility is critical in your research. Identify key criterial for your antibody and receive fully characterized antibodies that meet those specifications.

  • Specificity confirmation by direct ELISA
  • Concentration determination
  • Purity by SDS-PAGE
  • Aggregation by SEC-HPLC
  • Cross-reactivity testing
  • Endotoxin levels by LAL
  • Custom fill and finish

Anti-Idiotype Antibody Development

Anti-idiotypic antibodies play a critical role in antibody drug development. Using our established processes, we can quickly design an immunization strategy to generate custom anti-idiotypic, customized antibodies specific to your antibody drug.

By understanding your goals, we will target antibodies for binding or blocking for your specific pharmacokinetic and immunogenicity studies.

Host Cell Protein Antibody Development

We can develop custom Host Cell Protein antibodies that are tailored to your cell line and specific to your process. Combine this with full assay development on our Luminex, Quantikine ELISA, or Ella platforms to provide an integral tool to your development process.

ProteinSimple Platforms

Simplify your sample analysis by utilizing our existing expertise in assay optimization on our ProteinSimple platforms. We will design an assay using our extensive antibody selection for rapid single cell or sample protein analysis. Explore our ProteinSimple platforms:

  • Simple Western – analyze proteins by size from 2-440 kDa
  • Simple Plex – automated immunoassays
  • Single-Cell Westerns – measure cell subpopulatons


Conversion of our traditional monoclonal to recombinant antibody offered immortal supply of a very high quality product. We also liked the feature of the recombinant technology to be able to exchange the constant chain between different species and the ability to express the antibody as Fab fragments.
