Hybridoma development testimonial
“We collaborated on a project for generating a monoclonal antibody that recognizes a one-amino-acid mutation in a cancer-associated cell-surface protein. Although the project was technically challenging, we succeeded in generating a hybridoma clone that produced the desired antibody. During the course of the project, we found additional clones that recognized adjacent epitopes and ProteoGenix proceeded to perform additional subclonings in order to ensure the delivery of clones that work perfectly. In summary, ProteoGenix always strived to ensure maximal product quality and customer satisfaction, and the account Manager provided prompt and competent support at all times.”

Case study: monoclonal antibody production for the detection of a human cell membrane protein
AIM OF THE PROJECT
A customer requested the production of a monoclonal antibody for the detection of a human cell membrane protein. Design of the antigen was particularly challenging as the protein was known to be difficult to express in mammalian cells.
Application guaranteed: Flow cytometry
ANTIGEN DESIGN AND PRODUCTION
A protein fragment estimated as the possible extra-cellular domain, and possible to express in mammalian cells, was designed.
The corresponding gene was designed and optimized for mammalian cell expression.
Mammalian cells were transfected with a plasmid expressing the target protein coupled to GFP.
Protein expression was performed both in HEK293 and in CHO cell lines. Final production was performed in HEK.
Production method: protein secreted in culture supernatant
Quantity produced: 0.86mg
A final QC was performed by SDS-PAGE.
ANIMAL IMMUNIZATION AND SCREENING
5 mice were immunized with 4 injections containing the protein antigen. More information about the protocol is available in the complete report.
FC results of the mice serum tested against the immunogen:
|Sample tested||Positive control||Mouse 3||Mouse 4|
|Mice serum after 3rd injection||90%||42%||29%|
|Mice serum after 4th injection||76%||47%|
Results for the other mice are available in the complete report.
Mouse 3 demonstrated the best immunogenic reactivity against the antigen in FC.
As our project includes 2 fusions, both mice 3 and 4 were selected to perform fusion.
SUPERNATANT SAMPLES AFTER FUSION (MOUSE 4): TEST IN ELISA
|Confirming screening after fusion|
24 positive clones were selected in ELISA.
Determination of the best clones for FC is done directly in the target application.
SUPERNATANT SAMPLES AFTER FUSION (MOUSE 4): TEST IN FC
Details about the protocol are provided in the complete report.
|FC result / %||37.48||1.27||20.27||62.50||1.18||11.40||1.38|
|FC result / %||75.09||1.01||6.50||56.76||73.16||1.18||1.09|
|FC result / %||1.07||1.05||1.49||6.75||71.92||1.18||1.02|
|FC result / %||1.04||1.01||7.36||80.73|
11 positive clones were obtained after fusion in FC. These clones were subcloned for further antibody production.
Similar ELISA and FC analyses were performed on mouse 3. 14 positive clones were obtained after FC. Results are available in the complete report.
30 clones were selected by our customer for further production. Supernatant samples were tested in ELISA and FC after 2 subcloning steps. Results are provided in the complete report.
We succeeded in producing a difficult-to-express protein in sufficient quantities to develop monoclonal antibodies. Several expression tests, with several mammalian cells strains, were performed to reach this goal.
The immunization protocol in mice allowed us to develop good antibodies against the antigen.
After 2 fusions, 30 hybridomas/clones detecting the antigen in flow cytometry were produced.
30 clones and 30 purified antibodies were delivered to our customer.

What are the advantages of hybridoma development for antibody generation?
Hybridoma technology revolutionized the whole biotechnological field by providing a method which is unlimited and reproducible monoclonal antibody production. Today, hybridoma development is still a reference method for high sensitivity antibody generation. Therefore, hybridoma technology remains the best technique assay development. It also represents a good alternative to phage display for therapeutic antibody development. However, administration of monoclonal antibodies produced by hybridoma technology leads to severe side effects due to their mouse origin. Thanks to recent advances in antibody engineering, the immunogenic mouse components can be reduced by a so-called antibody humanization process. Together affinity maturation, this global process can be highly relevant to generate optimized humanized antibodies suitable for therapeutic applications.
