Thymosin Alpha-1 vs TB-500
Two thymosin-family peptides with very different research uses.
Thymosin Alpha-1 and TB-500 both trace to thymosin biology, but they are distinct peptides — one studied in immune signaling, the other in tissue repair.
Side-by-side
| Attribute | Thymosin Alpha-1 | TB-500 |
|---|---|---|
| Type | Thymosin alpha-1 (28 aa) | Thymosin beta-4 fragment |
| Studied mechanism | T-cell and immune signaling | Actin regulation, cell migration |
| Research focus | Immunomodulation | Tissue repair |
| Form | Lyophilized powder | Lyophilized powder |
| Relationship | Different thymosin family | Different thymosin family |
Which does the research favor?
Despite the shared thymosin name, these are different peptides for different research — immune signaling for Alpha-1, tissue repair for TB-500.
