| A common neutralizing epitope conserved between the hemagglutinins of influenza A virus H1 and H2 strains. |
| It is possible for two or more different substances to have an epitope in common. |
| In contrast, they recognize epitopes of region A or an epitope present on both chains, A and B, in the event of insulin therapy. |
| Binding between the receptor and epitope occurs only if their structures are complementary. |
| If they are, epitope and receptor fit together like two pieces of a puzzle, an event that is necessary to activate B-cell production of antibodies. |
| In all the experiments on native titin, the molecule was attached to two beads, each labeled with an antibody to a different epitope. |
