Testimonial for ascites and hybridoma cell culture antibody production

Senior Scientist
at Pfizer

“One of our hybridomas was unstable, difficult to grow and with a poor antibody yield. ProteoGenix was able to rescue it and produce large scale batches of purified antibodies of consistent quality. We appreciated ProteoGenix’s hard work and commitment to successfully deliver this difficult project which was of critical importance for us.”

Manager at Agritest

“ProteoGenix is a reliable partner for supplying both 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.”

Ascites vs. hybridoma cell
culture antibody production

Production Method Production Method Pros Cons
Mouse Ascites 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
Hybridoma cell culture Medium With serum
  • Animal protection: no animal use, injection, sacrifice → more ethical
  • Almost same price + lead time as ascites production
  • Lower antibody concentrations than ascites, 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
  • Animal protection: no animal use, injection, sacrifice → more ethical
  • Better defined and reproducible medium formulations than serum medium → 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
  • Lower antibody concentrations than ascites, which requires concentrating steps that might change antibody affinity or denature antibody
  • 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 purified antibody contamination by animal components such as proteins → risk of interferences in experiments dramatically reduced
  • Best if purified antibody 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

  • Lower antibody concentrations than ascites, which requires concentrating steps that might change antibody affinity or denature antibody
  • More expensive + may take more time than serum/serum-free/ascites production

Hybridoma cell culture principle

Hybridoma cell culture is an in vitro alternative of ascites production. This technique does not require the use of animals and can produce antibodies free of contaminants (if produced in animal free medium).

Hybridoma cell culture consists in growing hybridoma cells and harvesting the culture supernatant (containing the antibodies). Briefly, the hybridoma cell culture occurs in two phases:

  • The first one is optimal for cell growing. This step is characterized by a higher presence of serum compared to the second step.

  • The second step is more optimal for antibody production as it contains less or no animal component depending on the option chosen (serum free or animal free culture medium).

It exists two different ways to adapt the hybridoma cell line to the antibody production medium:

  1. The direct adaptation: in this technique, the hybridoma cells are directly adapted from serum-containing medium to serum free medium.
  2. The sequential adaptation: the sequential adaptation is based on a progressive depletion of the amount of serum in the culture medium. It is generally used if the direct adaptation does not work.

The expected yield of hybridoma cell culture is around 10-50mg/L. If higher yields or high amount of antibodies are necessary, we would suggest using our recombinant antibody production service. Any doubt about the most relevant antibody production technique for your project? Check the following table or contact our dedicated account manager.

Ascites antibody production principle

Ascites production requires an available hybridoma cell line. This technique is an in vivo antibody production method based on the injection of hybridoma cells into the abdominal cavity of a rodent to produce ascites fluid. This fluid contains a high concentration of antibodies which can generally not be obtained by classical in vitro methods.

Despite these advantages, we would never advice our customers to order this technique except if there is no other alternative. Alteration of the antibody properties during the purification step could be such an exception. In this case, ascites antibody production could be necessary as the high concentration of the antibody produced allows the use of the ascitic fluid as is (without purification step).
