Examples

• The monospecificity of the vaccine ensures it targets only the intended pathogen.
• Researchers studied the monospecificity of the antibody to confirm its binding selectivity.
• The drug's monospecificity makes it effective against one bacterial species without harming others.
• Monospecificity in immune responses helps prevent unwanted cross-reactions.
• The test relies on the monospecificity of the monoclonal antibody for accurate diagnosis.
