We deliver antibodies that work in your intended application. Please contact us if you do not find a specific service item you are looking for. We can design and customize your project and generate the exact antibody you need.

Custom Antibody Development

  • Novel monoclonal antibody development in just 40-60 days! Precision Antibody uses its proprietary procedures and platform to rapidly generate application specific monoclonal antibodies (mAbs). Precision Antibody customizes project strategies to ensure the delivery of mAbs that work in the intended applications.

    Precision Antibody has developed numerous antibodies for:

    • Diagnostic applications (Sandwich ELISA, Lateral flow, Flow cytometer, IHC, and others)
    • Therapeutic applications (Neutralizing, Agonistic, and Internalizing)
    • Anti-Idiotypic antibodies (anti-Paratopes and Idiotopes
    • Neo Epitope-specific antibodies (Post-translational modification sites and Cleavage Site)
    • Immuno-MRM (Mass Spec)

  • Rat and mouse polyclonal antibody development service: At times you may encounter the situation “I needed that antibody, yesterday!!” Well, PA cannot reverse the time to accommodate your needs, but we offer the next best option and develop high-affinity hyperimmune serum in less than 3 weeks using mice or rats. Affinity purification will add additional 7-10 days. The development of rat polyclonal antibody is the most popular option for many of our customers. Due to the high specific IgG titer we achieve, even a smaller amount of serum goes a long way in your research.

    Rabbit polyclonal antibody development service: PA offers traditional rabbit polyclonal antibody development service. We have 60 or 90-day protocols and continuous production of antibody is possible.We also offer antibody purification services from rabbit polyclonal serum. (see Antibody Production and Purification section)

    Please contact our specialist for rabbit polyclonal service.
    For immunization of larger animals, please inquire.
