Ascites production and purification


As a monoclonal and polyclonal antibody expert, ProteoGenix offers all related services such as ascites production and purification from mice. We can produce antibodies on a small or large scales in ascites, even though we recommend producing culture supernatants for large scale production. You can provide your own hybridomas or let us develop new hybridomas to use for your Ig production request.

Production in culture supernatant


As part of our custom antibody services, we produce antibodies from culture supernatants either from hybridomas developed by ourselves or hybridomas provided by our customers. We can produce milligrams to grams of purified antibody using serum, serum-free or animal-free culture medium depending on your needs. We have various technologies available for production, such as flasks, roller bottles, hollow fibers, wave bags and bioreactors.
ProteoGenix can also check your antibodies for mycoplasma, identify the isotype, define the best production method, make pilot production runs, or produce master and working cell banks.

Download this form and send it to us by email at [email protected]. We will reply with your quote in 24 hours. You can then send your PO to order any antibody production and purification in cell culture.

Pros and cons of the different antibody production methods offered by ProteoGenix


Production MethodProsCons
Mouse Ascites
  • Best and easiest for hybridomas
  • Stable antibody yields + very high antibody concentrations
    → purification easier + no further concentration procedures required
  • Animal use
  • Purified antibody can contain residual mouse contaminants such as IgG
Cell Culture SupernatantMedium With serum
  • Animal protection: no animal use, injection, sacrifice
    → more ethical
  • Almost same price + lead time as ascites production
  • Low antibody concentrations, which requires concentrating steps that might change antibody affinity or denature antibody
  • Purified antibody can contain residual animal contaminants such as IgG
Serum-free Medium
  • Better defined and reproducible medium formulations
    → higher antibody yields + more consistent productions
  • Elimination of a source of possible infectious agents (viruses, prions, bacteria)
  • Reduction of purified antibody contamination by culture residues such as animal IgG
    → reduced risk of interferences in experiments
  • Much cheaper than cultures with ultra low IgG serum
  • Potential persistence of residual animal contaminants in purified antibody
  • More expensive + may take more time than serum/ascites production
Animal-free Medium


  • Same as serum-free but with 100% elimination of other animal contaminants
  • No risk of end product contamination by animal components such as proteins
    → risk of interferences in experiments dramatically reduced
  • Best if end products to be used for in vivo experiments


Synonyms: Animal-product free (APF), animal component-free (ACF), animal-derived component-free (ADCF), non-animal origin medium

  • More expensive + may take more time than serum/serum-free/ascites production

Ascites & Culture Supernatant Production Testimonial


“ProteoGenix is a reliable partner for supplying either in vitro and in vivo mAbs. I appreciated the collaborative and prompt problem solving attitude of the management, which definitely added value to our deal."
