What Makes A Good Antibody?

Boster Antigen design and expression overview


We will design the antigen using our decades of experience in immunogen design, taking consideration of a variety of factors including sequence homology, post-translational modification, secondary/tertiary structure and epitope localization.


We recombinantly express the antigen with our proprietary protein folding technique to ensure best tertiary structure accuracy of the antigen to the target protein’s natural form.

Available Hosts

Although this is a custom rabbit polyclonal service, alternative hosts such as guinea pig, chicken, and goat are available if needed for your project. Please inquire.

Additional Services

Pre-immune screening

  • Order a vial of pre-immune serum for screening existing immunity against the target protein, and for control purposes.*
  • Price: $100 per rabbit, 1ml of serum, not purified

  • Order a vial of test serum after each of the immune booster shots to verify immune response’s antigen specificity and Ig isotypes.
  • Price: $50 per rabbit per bleed, 1ml of anti-serum, not purified

Additional rabbits

  • Order additional rabbits to improve the yield and success rate of your project. If the rabbit is positive and passes QC, 2mg of antibody will be added to your final deliverable.
  • Price: $200 per rabbit

Additional antibodies

  • If there are remaining antibodies from the batch, additional antibodies are available for purchase.
  • Price:
  • $150 for additional 100ug
  • $500 for additional 1mg
  • $1000 for additional 10mg (if available)

Blocking Peptide

  • If you require a blocking peptide for your developed antibody, we can help you with that.
  • Price: $150 for 1mg of blocking peptide

Recombinant Protein

  • If you want the recombinant protein we generated for you, you can purchase it from us.
  • Price: $200 for 1mg of purified recombinant protein. Inquire for bulk pricing.

Specific Application Insurance

  • Purchase an insurance for your antibody to work for certain applications.
  • Price: Custom, depending on the application and nature of the target protein

Intellectual Property & Exclusivity

  • If you intend to have exclusive rights for the produced antibodies, we can create a license that fits your needs.
  • Price: Custom, depending on the intended use of the antibody

*Why do I want pre-immune sera? Sometimes antibody immunization fails because some hosts have existing immunity towards your target protein of interest. This is especially common if the protein originated from organisms is related to common pathogens. Screening the hosts’ sera against your protein of interest can help mitigate this risk.
