Scientific Details
Thymosin α1 (also designated Thymalfasin in research literature) is a synthetic 28-amino-acid acetylated peptide originally isolated from thymic tissue, now supplied as a defined synthetic reference material for laboratory research. The peer-reviewed literature catalogs Thymosin α1 across immunomodulator-pathway investigations, T-cell maturation pathway studies, Toll-like receptor (TLR) signaling research, and antimicrobial-pathway investigations in cell-culture and animal-model contexts. Its molecular identity is fixed by sequence and structural confirmation against PubChem CID 16130571, empirical formula C129H215N33O55, with CAS Registry Number 62304-98-7. The reference material supplied here is intended for laboratory characterization, in-vitro receptor-binding work, and in-cell signaling studies only. For research use only; not for human consumption, medical use, or veterinary application. Researchers should consult primary literature for context-specific experimental conditions.
Thymosin α1 is a 28-residue peptide with an N-terminal acetylation modification that confers resistance to aminopeptidase cleavage. The molecule's interaction profile in the published literature spans engagement with Toll-like receptors — particularly TLR2 and TLR9 — and downstream signaling through MyD88-dependent pathways documented in cell-culture studies. Pharmacokinetic descriptors documented in published animal-model investigations include rapid plasma clearance and short systemic residence under standard parenteral paradigms. Interaction profile in the literature also spans T-cell differentiation in thymocyte preparations, dendritic-cell signaling investigations, and cytokine-pathway intersection in immunomodulator research. All activity descriptors here are framed as documented in published research rather than as effects of the supplied product. Structural confirmation of supplied lots is established by mass spectrometry molecular-ion match to the C129H215N33O55 empirical formula, with HPLC-validated purity reported on each Certificate of Analysis.
Experimental domains documented in the published literature include Toll-like receptor binding studies, MyD88-dependent signaling assays in dendritic-cell models, T-cell differentiation and maturation studies in thymocyte preparations, cytokine-pathway investigations in immune-cell cultures, antimicrobial-pathway research in animal-model contexts, and structure-activity work probing the role of N-terminal acetylation in proteolytic stability. Investigators have also characterized Thymosin α1 in comparative studies alongside other thymic-derived research peptides and in screening assays for TLR-pathway-active peptides. Use in laboratory research extends to mechanism-elucidation paradigms where the molecule serves as a defined immunomodulator-pathway reference. The reference standard is supplied for these and equivalent in-vitro and animal-model experimental contexts only, with no associated guidance for human, clinical, or veterinary application. Researchers should consult primary literature when designing context-specific protocols.
Each lot is characterized by reverse-phase HPLC for chromatographic purity and by mass spectrometry for molecular-ion confirmation against the C129H215N33O55 empirical formula. Purity is reported as an HPLC-area percentage on the Certificate of Analysis distributed with every lot, alongside the molecular-weight match within instrument tolerance. The N-terminal acetylation modification is confirmed by tandem mass spectrometry when included in the lot's release specification. Peptide content where applicable is determined by amino-acid analysis or nitrogen-content assay following the analytical method specified on the COA. Residual solvent and water content are reported categorically when these parameters are part of the lot's release specification. The COA records the lot identifier, manufacturing date, and analytical method versions used. Researchers requiring batch-level analytical detail should reference the COA distributed with the supplied material.
For laboratory storage, the lyophilized reference standard should be held at −20°C in its sealed, light-protected container until ready for analytical use. Allow vials to equilibrate to ambient temperature before opening to avoid moisture condensation on the lyophile. Reconstitution for in-vitro experimental use is typically performed in bacteriostatic water or a researcher-selected buffer compatible with the downstream assay; once reconstituted, store the working solution at 2–8°C and characterize stability in the relevant buffer prior to extended storage. Avoid repeated freeze-thaw cycles of reconstituted material — single-use aliquots are preferred for experiments where peptide integrity is assay-critical. These handling parameters reflect general best-practice for lyophilized peptide reference standards and do not constitute preparation guidance for human or veterinary application.
