1. Optimization and purification of seed toxin antigens
By optimizing the breeding technology through dilution cloning, the optimal strain with high immunogenicity was screened. By using continuous centrifugal separation and ultrafiltration technology, impurities in the production process are removed, resulting in purer antigens.
2. Joint synergistic immunity and cross protection of multiple toxins for full coverage
The synergistic immunization of multiple strains effectively improves the overall protection and prolongs the duration of antibodies after use, providing a wider cross protection range against different wild-type viruses and exhibiting good immunogenicity against different strains of animals.
3. Scientific and efficient antigen matching
Single embryo vaccination with a single antigen, utilizing advanced molecular biology techniques to optimize antigen ratios and generate synergistic effects, resulting in a more efficient vaccine.
4. Selected SPF eggs, pure and safe
Secondary selection of qualified SPF eggs, using only selected chicken embryos of uniform specifications, resulting in purer and safer vaccine products.
