Custom Antibody Services

Your Antibody, Our Expertise

Generation of new 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 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.

Custom Antibody Conjugation Services

Apply our decades of conjugation experience to your project. Our scientists will apply the appropriate protocols to your project to ensure the final conjugate meets your needs. From detection antibodies for immunoassays, to flow cytometry conjugates, we can provide small to large scale antibody conjugation with a fast turnaround and fully tested end material. Available conjugates include:

  • Biotin
  • HRP
  • Alkaline Phosphatase
  • Alexa Fluor® 350, 405, 488
  • Alexa Fluor® 647, 700, 750
  • 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


Manufacturing and GMP Conversion

Using established procedures, we manufacture custom antibodies for drug discovery, diagnostic, and cell ex vivo use under research or GMP regulatory requirements. All GMP custom antibody manufacturing is completed recombinantly and starts with conversion of your hybridoma-derived antibody to an immortal recombinant antibody.

Ensure a consistent supply of your critical antibody through our established scale up and manufacturing processes.


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 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 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.

Principal Scientist, Biotech Company

Baseline samples taken one week apart from 15 cynomolgus monkeys were obtained from a Genentech study conducted at Charles River Laboratories (Reno, NV, USA). Positive controls from three sources were used: human IgG-cyno IgG fusion molecule produced for Genentech at R&D Systems (Minneapolis, MN).
