Overview
Thymosin alpha-1 (thymalfasin) is a 28-amino-acid peptide, N-terminally acetylated, corresponding to a fragment of the precursor protein prothymosin alpha. It was the first thymic peptide to be sequenced, and its defined structure (C129H215N33O55; 3108.3 g/mol) makes it a well-characterized immunomodulatory research peptide.
In preclinical and in-vitro research, thymosin alpha-1 has been studied for its effects on immune-cell signaling, including modulation of T-cell function and Toll-like-receptor-associated pathways. A chemically synthesized form identical to human thymosin alpha-1 has been approved in a number of countries as an immunomodulating therapeutic in specific indications; that approval status is contextual background and is distinct from the research-only material offered here.
BioTech Pharma supplies Thymosin alpha-1 as a lyophilized powder intended solely for laboratory research; it is not offered for human or veterinary use. Lot-specific analytical documentation may be available and should be confirmed for the applicable material.
Research Applications
- Immune-cell signaling and T-cell modulation studies
- Toll-like-receptor pathway research
- Cytokine-response and inflammation models
- Prothymosin-alpha fragment structure–function work
- Tissue-response and host-defense research models

Analytical Data
Lot-specific documentation may be available for the applicable material and must be confirmed per enquiry. Where available, it may include:
- HPLC purity result
- LC-MS identity confirmation
- Appearance
- Net content
Request the records you need with your quote and we will confirm availability for your batch.
Procurement Details
Availability, lead time, salt / content basis, and cold-chain requirements depend on the specific lot and quantity, so we confirm them per enquiry rather than publishing fixed figures. Request confirmation for your requirements with your quote and our team will respond with details for the applicable batch.
Storage & Handling
Lyophilized: store sealed at −20 °C, protected from light and moisture. Reconstituted solutions should be kept refrigerated (2–8 °C); prepared-solution stability is lot-specific and should be determined empirically for each application. Prepared-solution stability should be confirmed for the applicable material.
