Peptide immunization

Peptide immunization elicits specific immune responses based on precisely screened antigenic epitope peptides, with five core advantages as follows:

• Superior targeting precision. It can distinguish protein modifications, isoforms and mutation sites, and simultaneously activate dual immunity consisting of humoral response and cytotoxic T cell response.

• Low safety risks. Peptides are purely chemically synthesized with no risk of infection, and free from severe allergies or off-target inflammation induced by impure foreign proteins.

• Flexible design and modification. Tandem multi-epitope construction and site-specific modification enable rapid multi-target combined immunization, solving the challenges of immunizing hard-to-express proteins.

• Simplified production and quality control. The synthesis process delivers stable performance and excellent batch consistency, with lower barriers for storage, transportation and overall costs.

• Favorable small-molecule permeability. Peptides are readily taken up by immune cells. This technology serves as the preferred vector for next-generation precision immunization, applicable to personalized vaccines for tumors and infectious diseases as well as the development of specific antibodies.

Peptide antigens are adopted for immunization based on target analysis. The immunization procedure and timeline are shown below:
