Thymalfasin
Price range: AUD66 through AUD119
Thymalfasin is the international non-proprietary name (INN) for the synthetic form of the 28-amino-acid thymic peptide Thymosin Alpha 1. It is classified as an immunomodulatory thymic peptide and is manufactured by chemical synthesis to a defined, reproducible sequence. Thymalfasin is supplied exclusively as a laboratory research reference material for immunological studies.
Research Background
Thymalfasin has been investigated as a synthetic reference standard for research into thymic peptide activity. Studies have examined its reported role in modulating immune signalling, including the maturation of T-lymphocyte subsets and interactions with innate immune receptors. Because it is produced synthetically rather than extracted from tissue, Thymalfasin offers researchers a highly consistent material for reproducible experimental work on immune-cell function.
Investigators use Thymalfasin as a benchmark in comparative immunology, cytokine-pathway research, and studies of how defined thymic peptides influence cellular signalling in controlled in vitro systems. Its identical sequence to naturally derived Thymosin Alpha 1 makes it valuable for validating experimental results across preparation methods.
