Novoprotein’s recombinant monoclonal antibody production gives you these advantages:
Complete Service Package:
From antibody sequencing to recombinant antibody production, and in vitro hybridroma production
Risk-Free Antibody Sequencing:
Free RNA isolation, satisfaction guaranteed, quick turn-around
High Yield and Low Cost:
Our proprietary mammalian expression system produces up to 100mg/liter in transient transfection system
Gram scale on a monthly basis
Recombinant antibodies are expressed with our mammalian system, from the antibody gene, completely eliminating animals from the antibody-production process. Recombinant antibodies can be used in all applications where traditional mAbs are used, and its production has several advantages over traditional mAbs: Fast: Recombinant Abs can be produced in 8 weeks, drastically shorter than months required for hybridoma-based methods. Highly controlled: The unpredictable process or changes in host animals are avoid during the production of recombinant antibodies. Excellent for reproducibility: The strict batch-to-batch consistency gives you reproducibility of experiments. Safe: Recombinant antibodies are anima-free, therefore unlikely to stimulate immune response.
