Thymosin Alpha-1

Thymosin Alpha-1 – Research Grade

Thymosin Alpha-1 from Cleared Peptides is a research-grade compound supplied for laboratory and analytical investigation. Every lot is third-party tested, and the batch Certificate of Analysis is published before sale. Specifications, CAS number and molecular formula are listed below.

Research use only. Thymosin Alpha-1 is supplied for laboratory research. It is not a drug, food, cosmetic, or dietary supplement. It is not FDA-approved. It is not for human or veterinary administration. This page does not give a dose or a method of administration. A study cited on this page describes that study’s own test article. It does not make this lot an approved medicine. To check a fact, open the PubMed or DOI link, confirm the authors and year, and match the paper’s compound name, CAS number, or sequence to the specification table. The full method is on the research desk page. Identity and purity for a lot are only what that lot’s certificate of analysis reports. An HPLC percentage is not a sterility result and not an endotoxin result unless the certificate prints those tests.

Thymosin Alpha-1 Specifications

Thymosin Alpha-1 in Published Research

Thymosin Alpha-1 (thymalfasin) is a 28-amino-acid N-acetylated peptide originally isolated from thymic tissue (thymosin fraction 5).

It is used in immunology research, including toll-like-receptor signaling and T-cell maturation studies in cell-based models.

This summary describes published laboratory research only and makes no claim about effects in humans or animals.

Purity Testing & Certificate of Analysis

Each lot of Thymosin Alpha-1 is analyzed by an independent laboratory, with identity and purity (or composition, for multi-component preparations) reported on a lot-specific Certificate of Analysis. View current results on our COA page.

Storage & Laboratory Handling

Store at −20 °C, sealed, dry and protected from light. Allow vial to reach room temperature before opening. Minimize freeze–thaw cycles and handle according to your institution’s chemical-hygiene procedures.
