Recombinant monoclonal antibody

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

  • Large-Scale Capacity:

    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.

Large-scale monoclonal antibody production and purification
  • Strategy design

    • Genes encoding heavy and light chains of the antibody were constructed into Novoprotein high expression plasmids.
    • Confirm by sequencing.
    • Small scale expression and purification.
    • Sample sent to customer and large scale production initiated.
  • Deliverables:

    • 100mg antibody was produced with concentration >2mg/ml, purity>90% as estimated on SDS-page.
  • 1. Small scale expression

    Fig. 1 SDS-PAGE analysis of small scale expression.
    1-3: 72-120 hour expression; 4: expression control GFP
  • 2. Purification of antibody by protein A column
