Thymosin Alpha-1 (Tα1) – High Purity Research Peptide
Thymosin Alpha-1 is a synthetic version of a naturally occurring peptide fragment derived from prothymosin alpha, a protein found in the thymus gland. This peptide is widely studied in scientific and clinical research for its potential role in modulating immune system activity.
Known for its stability and high bioactivity in laboratory conditions, Thymosin Alpha-1 is used in research exploring immune response pathways, cell signaling, and potential therapeutic applications. Researchers often focus on its interactions with T-cells and its effects on cytokine production.
Key Features:
≥99% purity (HPLC tested)
For laboratory research use only

Quality Standard
Purity is the percentage of your peptide that is actually the intended compound. Everything else is contamination — and contamination changes your results.
What's in the other ~2.7%?
Synthesis Byproducts
Failed or incomplete chains produced during manufacturing that mimic your peptide but behave differently in research.
Residual Solvents
Chemical solvents used in the production process that aren't fully removed during purification.
Misfolded Chains
Peptide chains that assembled in the wrong sequence or orientation — structurally different from what you ordered.
Endotoxins
Bacterial contamination introduced during handling that can trigger inflammatory responses and skew results.
