Polyclonal antibody

Novoprotein’s polyclonal antibody production gives you these advantages:

  • Free Antigen Design:

    Our in house experts with extensive experience design optimal antigens based on your applications and antibody characteristics.

  • Flexible Antigen Choices:

    We generate antigens as peptides or recombinant proteins based on your budget and protein properties.

  • 10-Week Immunization Protocol:

    We immunize two rabbits in parallel for 10 weeks with a boost every two weeks for the best antibody production.

  • Guaranteed ELISA Titer Result:

    We only charge our customers when the antibody has greater than 1:8000 ELISA titer.

  • Deliverable:

    minimal delivery is 10mg with greater than 95% purity.
