TA-1 is thymosin alpha-1 (Tα1), a 28-amino acid N-terminally acetylated thymic peptide that acts as an endogenous TLR2 and TLR9 agonist.
Research panels using Tα1 commonly examine innate-to-adaptive immune signalling transitions, dendritic cell maturation markers (MHC-II, CD80/86 upregulation), and cytokine secretion profiles (IFN-α, IL-12) in primary PBMC or monocyte-derived dendritic cell models. It is also used as a positive control in TLR agonism reporter assays.

In research literature, TA-1 is generally treated as thymosin alpha-1 (Tα1), a 28-amino acid N-terminally acetylated thymic peptide that acts as an endogenous TLR2 and TLR9 agonist. Tα1 is naturally secreted by thymic epithelial cells and has been characterised as an agonist at Toll-like receptors 2 and 9 (TLR2, TLR9) in dendritic cell and macrophage assay models, activating downstream MyD88-NF-κB and MAPK signalling pathways. In T-lymphocyte assays it is studied for enhancement of CD4+ T-helper cell differentiation and NK cell cytotoxic activity. Unlike many immunomodulatory peptides, Tα1 is defined by an N-terminal acetyl group on its Ser1 residue — loss of this modification substantially reduces biological activity in receptor-based assays, making N-terminal integrity a critical quality attribute to verify before functional experiments.
Research panels using Tα1 commonly examine innate-to-adaptive immune signalling transitions, dendritic cell maturation markers (MHC-II, CD80/86 upregulation), and cytokine secretion profiles (IFN-α, IL-12) in primary PBMC or monocyte-derived dendritic cell models. It is also used as a positive control in TLR agonism reporter assays. For laboratory teams, the practical emphasis is usually on sequence identity, receptor or pathway relevance where documented, and whether TA-1 behaves consistently across stability, purity, and analytical verification workflows. Variant labels on this page support clearer internal referencing when multiple labelled variants are under review.
Potential research applications for TA-1 should be framed strictly in analytical and laboratory terms. Typical reasons a team might review this product page include:
Handling decisions should always follow the vial label, internal SOPs, and any product-specific documentation. A conservative laboratory baseline for TA-1 is:
If a product-specific file is not attached to this listing, the wider COA library remains the correct reference point for current published documentation. The COA section is useful for confirming how the product is labelled in the catalogue, whether purity information has been published, and whether the laboratory record for the material is complete before bench use.
When teams compare TA-1 with Melanotan 1, IGF-1 LR3, and Glow, COA access also helps keep comparator decisions grounded in documented material identity rather than assumption. That is especially important for research pages that combine pricing, variant selection, and analytical records on a single URL.

It brings together 1 labelled variant: 10mg, current pricing context, stock visibility, COA access, and internal links to related catalogue pages so a laboratory buyer can review the material from a single reference URL.
TA-1 is generally discussed as thymosin alpha-1 (Tα1), a 28-amino acid N-terminally acetylated thymic peptide that acts as an endogenous TLR2 and TLR9 agonist. The most relevant background is sequence behaviour, pathway or receptor context where documented, and analytical consistency under controlled laboratory conditions.
Use the label, COA, and internal SOPs as the primary guide. In general, store the material under controlled laboratory conditions, minimise avoidable environmental exposure, and keep variant tracking records current.
This page links the broader COA library when a product-specific document is not attached. Laboratories should use the published documentation set that is currently available for the listing.
No. The page should be interpreted strictly in a research and laboratory context. It does not provide dosage guidance, treatment claims, or human or animal use instructions.
