Custom Antibody Development
Hybridoma development for new antibody producing cells

Biometec offer a step by step service for generation of monoclonal antibody producing cell lines to make it easy for you to plan the experiments and save costs. Together we can start and stop the antibody development after each step and you have to pay only the finished step.

The standard protocol can be adapted at customers’ option.

 

Standard protocol

Step 1 - Immunisation of 3 BALB/c mice with your antigen and standard protocol

Sera from mice will be tested by ELISA using immunogen. Once an acceptable titre is obtained cell fusion will be done using splenocytes from mouse with the best titre. Alternatively you can try an in vitro immunisation of spleen cells (for toxic antigens).

Antigen requirements: 2 mg for immunisation and 3-5 mg for screening

 

Time 4-8 weeks

Price 1000 Euro including fusion preparation and veterinary licence

 

Step 2 - Hybridoma generation and screening of specific clones

Splenocytes from spleen of the best mouse are fused with mouse myeloma cell line. The fused cells are plated into five 96well plates. After hybrid selection wells with growth are screened for specific antibody production by ELISA two times. The antibody positive clones are isolated and safety cryoconservated one time. Now the best stable 10-15 antibody producing primer cultures will be cryopreservated 5 times.

 

Time 3-4 weeks

Price 2000 Euro

 

Step 3 - Subcloning

Positive wells are subcloned three times by limiting dilution method and tested in each time by antigen specific ELISA.

 

Time 4-6 weeks

Price 2000 Euro for 5 clones

 

Step 4 - Expansion and cryopreservation

Test for recultivation, Isotyping, mycoplama testing

 

Time 2-4 weeks

Price 1000 Euro for 5 clones
