Introducing Abcepta "Crown" Antibodies!

Products labeled with a “Crown” meet stringent requirements in terms of specificity, sensitivity, and reproducibility.

  • All western blots show bands at the correct molecular weight, and any deviation or additional bands have been verified to be due to post translational modifications, isoforms, or cleavage.
  • Results are supported by peer reviewed literature and/or by the most relevant bioinformatics sites, i.e. Human Protein Atlas.
  • Many of these products are validated and optimized in additional applications including immunofluorescence and subcellular localization is verified using peer reviewed literature.
  • New lots are verified to perform as well or better than the previous lots in each application and species tested.


Abcepta is committed to preserving our natural resources and the environment. As part of this effort, we provide you with digital versions of all our brochures and posters below. However, if you prefer ordering a printed version, please fill out the form with your information and we will be happy to mail you one.

ELITE™ Polyclonal Antibody Services

Abcepta is a leading manufacturer of custom antibodies with over 20,000 antibodies developed over the last decade. Our team applies decades to offer tailored, flexible solutions producing antibodies matched to your needs. Provide your own immunogen or work with our world-class synthetic peptide chemistry group to design an epitope-specific and immunogenic peptide to meet your specifications for yield, purity, and target specificity. Our experience applies across a broad range of antibody applications, from workhorse Western Blot reagents, up to robust polyclonal anti-drug antibodies (ADA) used as positive controls for serum analysis as part of biotherapeutic safety assays.

Additionally, Abcepta can develop a pre-optimized antibody validated in the assay of your choosing. Please contact us to learn more about these and other service offerings.

Anti-Drug Antibody (ADA) Service

All biopharmaceuticals are immunogenic and may induce anti-drug antibodies (ADAs). The clinical effects of ADA formation can be highly variable and may cause severe adverse events that put the patient at risk. When designed correctly, high affinity ADAs can be ideal for use in pharmacokinetic bridging ELISAs and as reference standards in ADA assays. It is therefore imperative to develop ADAs with the appropriate sensitivity, specificity, and selectivity to guide biotherapeutic drug development decision-making.

Abcepta provides a fast and customer-oriented custom ADA generation service to support the clinical development of biotherapeutic drugs. Our approach is to first evaluate the customer’s most critical factors for each individual project, and then present tailored protocols and project management for approval. Allow Abcepta to be a part of your team!

ABCEPTA specializes in antibody production and has extensive experience
in the development of anti-drug antibodies, including development of anti-idiotype antibodies.

ABCEPTA CASE STUDY: Monoclonal Anti-idiotype Antibodies

The concentration of Anti-ID Ab is 37ng/mI, and the concentration
of negative controls (HuIgG1k) is 1 ug/mI
(Data from customer)

Anti-ID Ab initial concentration is 1ug/mL. Anti-ID Ab binds specifically to
idiotype Ab, but not other negative controls (HuIgG1k).

ELITE™ Modification-state-specific Antibody services

Phospho-specific antibodies are critical tools used for research of signaling pathways and regulatory networks in various cellular processes. Abcepta has vast experience in the development of custom and off the shelf antibodies against specific phosphorylated residues in different protein targets.

Additionally, Abcepta can also develop polyclonal /monoclonal antibodies against methylated and acetylated residues, valuable tools in epigenetics research.
