Antigen Discovery
Pathogen Study
In the discovery stage, quickly obtaining the pathogen gene sequence is usually the first critical step for developing vaccines and therapeutic drugs. The next step is to study the mechanism of the pathogen's entry into cells and its structure, function, and immunogenicity. The epitope (also known as antigenic determinant) is the part of the antigen recognized by the immune system that stimulates the immunogenic response. Therefore a deep understanding of the epitope distribution and types provides an essential foundation for vaccine development.
Tumor Study
With the development of immunology research, scientists and physicians have discovered new uses for vaccines, such as to treat some intractable diseases. Therefore, vaccines can have both preventive and therapeutic functions. Therapeutic vaccines belong to specific active immunotherapy, especially tumor therapeutic vaccines are at an important stage of development.
Tumor Specific Antigen Screening
Vaccine Development
Through the years, vaccine technologies have undergone many evolutions, and new vaccine types have been developed. GenScript provides comprehensive solutions for the development of new generations of vaccines, such as recombinant protein vaccines, peptide vaccines, mRNA vaccines, DNA vaccines, and viral vector vaccines.
Pre-clinical Study
In response to vaccination, the immune system develops innate and adaptive immune responses. The innate immune response is triggered immediately to new pathogens not present in the host. The more specific adaptive immune response is developed later and consists of antibody and cellular response. Therefore the level of the vaccine antigen is important in order to generate sufficient adaptive immune response. GenScript can support vaccine development as well as the development of vaccine-specific measuring assays such as neutralizing ELISAs and pseudovirus neutralization tests.

Clinical Development
The focus of clinical trials is to investigate the safety and effectiveness of vaccines, including the evaluation of vaccine protection efficacy and the exploration of the correlation between immunogenicity indicators and protection. Therefore vaccine samples for clinical trials should be produced under GMP conditions. GenScript can provide RUO and GMP grades of key materials used in vaccine development in research and clinical stages to fully support you in successfully launching vaccines.
