What is "antigenic"

Usage examples of "antigenic".

What she had done instead was identify the short string of amino acids, peptides, that folded up to form the actual antigen of the viral protein, map out the amino acid sequence, and then bio-facture a combination of different peptides, matching different regions of the viral protein, in the hope that one or more of the synthetic peptides would fold up to mimic an antigenic site present on the viral protein.

We've got a team working on amino acid sequencing, another working on protein sequencing, and Doc Pol and his apprentices are helping us to measure the antigenic distances between humans, Cuddlies, and a number of primates whose serum albumin we've been able to clone from our diskworld biological samples.
