What is Thymosin Alpha-1?
Thymosin alpha-1 is a 28-amino-acid acetylated peptide originally isolated from thymic tissue, where it is processed from prothymosin alpha. It is studied for its effects on T-cell maturation and dendritic cell signalling, largely through toll-like receptor pathways. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.
What is Thymosin Alpha-1 studied for?
- T-cell maturation assays
- Toll-like receptor signalling studies
- Dendritic cell activation research
- Immune modulation models
All applications above are in-vitro or preclinical research contexts. Thymosin Alpha-1 is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot THY-2609-X show?
Every lot of Thymosin Alpha-1 is tested by an independent US laboratory before it is listed. The report for lot THY-2609-X is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot THY-2609-X result |
|---|---|---|
| Identity | LC-MS | Matches the calculated mass for the sequence |
| Purity | HPLC-UV, 220 nm | 99.0% |
| Net peptide content | Amino acid analysis | Stated per vial on the certificate |
| Endotoxin | LAL, chromogenic | < 0.5 EU/mg |
| Sterility | USP <71> | Pass |
How is Thymosin Alpha-1 handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within the 28-day window on the certificate. The reconstitution guide covers volumes and syringe units and the concentration table gives the numbers for this vial.
Frequently asked questions
How does thymosin alpha-1 relate to thymosin beta-4?
Only by the shared historical name. They come from different precursor proteins and act on unrelated systems: alpha-1 on immune signalling, beta-4 on actin.
Is it the same as the thymus extract preparations?
No. This is a defined synthetic 28-mer with a known sequence, not a tissue extract.
Is Thymosin Alpha-1 for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
