Homology Considerations:<\/strong><\/p>\n\n\n\n

Two basic strategies can be used to address peptide antigen design. Both approaches should be considered when analyzing the protein sequence.<\/p>\n\n\n\n

    \n
  1. A unique sequence or region should be selected to ensure the specificity of the target protein.<\/li>\n\n\n\n
  2. A homologous sequence should be chosen so that a single antibody can recognize multiple proteins.<\/li>\n<\/ol>\n\n\n\n

    Epitope Selection:<\/strong><\/p>\n\n\n\n

    Continuous Epitopes, Discontinuous Epitopes:<\/strong><\/p>\n\n\n\n
