Recombinant Antibodies

ProMab Biotechnologies has been dedicated from the first day to develop monoclonal antibodies of the highest quality. We have invested in the recombinant antibody technology to effectively immortalize the best hybridoma clones. This has given us the ability to extend our antibody engineering capabilities, including the generation of bispecific antibodies.


Included in Custom Package

  • Antibody variable region synthesis and cloning
  • Antibody fragment (Fab, scFv, chimeric) validation via western blot and SDS-PAGE
  • Functional validation (options for ELISA, Biacore SPR, WB, IHC, FACS, etc)
  • Large scale production

Starting at $6,500

Generating a recombinant antibody requires expertise in antibody engineering. Our team has decades of antibody engineering experience that helps create a recombinant antibody that works for the intended application.
