How to choose the best
custom monoclonal antibody development technology for your project?

Choosing the best monoclonal antibody discovery technology can be critically challenging and can greatly impact your project’s success. Benefit from our long-standing experience in monoclonal antibody development to get the adapted solutions to your needs. The table below establishes a comparison between the different technologies considering several relevant parameters such as time requirement, cost, possibility of identifying difficult binders, antibody developability…etc.

Color legend: +++: good performance, ++: medium performance, +: low performance

Once monoclonal antibody production is chosen, the next step is to determine which antibody generation method is the most relevant. Basically, hybridoma and phage display remain the 2 most popular technologies. The final choice will depend on several parameters.

Depending on your budget, time, and the importance of your monoclonal antibody production project, we can advise to go for both antibody phage display and hybridoma development in parallel in order to obtain a wider range of clones and increase the probability to succeed to get the perfect antibody.

Hybridoma technology is highly relevant for monoclonal antibody generation with high sensitivity for the target antigen. Thus, this antibody production method is the reference for assay development. Due to its lower price compared to phage display, hybridoma development represents also a good alternative for therapeutic antibody development. In this context, our hybridoma development service can be associated to our antibody humanization and affinity maturation services to get an optimized humanized antibody.

In most of cases, antibody phage display will be the preferred method for therapeutic antibody development. Phage display is based on cDNA fragments obtained from the mRNA isolated from B lymphocytes. B lymphocytes can originate from various species without any restriction, including humans. The cDNA coding for VH and VL segments can be cloned in an expression vector next to a protein of a bacteriophage (usually pIII, pVII or pVIII) before infecting E. coli. This results in large libraries (~1010) which can be screened indefinitely for new antibody generation.

Antibody phage display for therapeutic antibody discovery offers several advantages:

  • High antibody diversity depending on the size of libraries,
  • Possibility to screen directly human libraries (direct access to fully human antibodies),
  • Possibility to screen toxic antigens,
  • Fast process including fast access to the antibody sequence and to recombinant antibody production,
  • No animal use once the library is made.

Single b cell sorting is a good compromise between hybridoma development and phage display. This technology incorporates a number of advantages specific to the two technologies mentioned above, such as obtaining high-affinity antibodies linked to the immunization process and preserving a natural VH/VL pairing leading to maximized antibody developability. These combined elements make it a method of choice for various fields of research, as well as for therapeutic or diagnostic antibody projects.
