Polyclonal Antibody Services
Advantages of our polyclonal antibody production system: low cost, high titer, high purity, and high yield.
- Free Antigen Design: our in house experts possess extensive experience in designing optimal antigens based on your applications and protein characteristics.
- Flexible Antigen Choices: we generate antigens as peptides or recombinant proteins based on your budget and protein properties.
- 10 WeekImmunization 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.
