1. Glycosylation of HA does not correlate with either the antigenicity or the selection pressure. 2. Doing this alters their antigenicity which allows them to have a more broad range of hosts. 3. They are also fragile and constantly replaced, sometimes with pili of different composition, resulting in altered antigenicity . 4. Preparation of the sample is critical to maintain cell morphology, tissue architecture and the antigenicity of target epitopes. 5. A chain shortened version of protamine also acts as a potent heparin antagonist, but with markedly reduced antigenicity . 6. Subsequent work showed that tumors escape immune recognition by losing their antigenicity in a process he named cancer immunoediting. 7. "P . gingivalis " is divided into K-serotypes based upon capsular antigenicity of the various types. 8. Other rhamnosides act as cytotoxic rhamnosylated terpenoids, as signal substances in plants or play a role in the antigenicity of pathogenic bacteria. 9. Then, the serum is incubated with RBCs of known antigenicity ; that is, RBCs with known reference values from other patient blood samples. 10. ASLV is divided into six subgroups, labelled A through E and J, each having a different antigenicity due to variances in viral envelope glycoproteins.
