Description
Thymosin Alpha-1 is a 28-amino-acid Nα-acetylated thymic peptide, originally isolated in 1977 from a calf thymus extract known as Thymosin Fraction 5. Also known as thymalfasin, LiveWell supplies it as a 500mcg research tablet, 60 tablets per bottle, strictly for in-vitro laboratory research.
Structure
Thymosin Alpha-1 has an acetyl group attached to its N-terminus, beginning with serine, and contains no cysteine residues or disulfide bonds — giving it a straightforward linear structure. It is classified as a thymic peptide, part of a family of compounds originally derived from the thymus gland.
