Mouse Monoclonal Antibodies

ProMab Biotechnologies dedicated itself from the first day to develop monoclonal antibodies almost exclusively.We have an onsite vivarium and working to establish a GMP facility soon. We keep a veterinarian on staff to make sure our mice and other animals are in the best health.




Included in Custom Package

  • Peptide Design
  • Immunization of 5 Balb/c mice
  • Western Blot screening with antigen
  • Evaluation of titer by ELISA
  • Screening of 10 clones by ELISA from an initial pool of 1000 clones
  • Sub-cloning and expansion of 2 clones
  • Antibody isotyping
  • 2 vials of hybridoma cells cryopreserved and stored for 6 months

We know how to generate an antibody that is specific to the immunizing antigen and that works for the intended application.

Our technical staff with decades of experience in immunology, biochemistry, and molecular biology will be there to guide your through the 10 to 14-week process.





* It is possible for certain antigens and certain mice to have stronger immune response than others. It typically takes 5 injections of antigen into mice for a mature immune response. Sometimes additional immunization boosts are required which can add another 2 to 4 weeks to the project. There are also times when it only requires 3 immunization boosts to get the desired titer.

Supernatant from 10 clones (or more if selected) will be sent to the client for in-house evaluation and use feedback to select 2 sub-clones (or more if selected). The Custom Mouse Monoclonal Antibody Package starts at $6,995.
