Prospective experimental validation
| Поле | Значение |
|---|---|
| Prospective | Improved antibody potency/resilience to viral escape reported |
| Tested designs | Multiple protein/antibody systems; exact count by system: paper-level extraction required |
| Success criterion | Improved antibody potency/resilience to viral escape reported |
| Main results | Improved antibody potency/resilience to viral escape reported |
Limitations
Requires credible complex structure; likelihood targets structural compatibility, not direct affinity; epistasis/multiobjective scope limited.
Что статья показывает
- Improved antibody potency/resilience to viral escape reported
Чего статья не показывает
- Predicted confidence, likelihood, pLDDT, docking or developability scores are not experimental affinity.
