01
Overview
Orthopoxvirus antigens are molecular components, typically proteins, found on or produced by viruses of the genus *Orthopoxvirus*. These antigens elicit strong neutralizing antibody responses and are targets for antibody detection, vaccine development, and antiviral therapies. Key antigenic proteins play roles in viral entry, immune evasion, and replication. Detection methods include ELISA-based assays, and variations in antigen sequences can affect cross-protection between different orthopoxviruses.
