TB-500 10mg

$54.99

TB-500 represents one of the most extensively studied regenerative peptides in modern biomedical research, serving as both a naturally occurring regulatory molecule and a powerful investigational tool for understanding tissue repair mechanisms. Originally identified as Thymosin Beta-4 (Tβ4) through groundbreaking research at the National Institutes of Health in 1981, this 43-amino acid peptide was first isolated from bovine thymus extracts and subsequently recognized as the most abundant intracellular protein in many mammalian cell types. TB-500, the commercially available synthetic derivative, contains the critical N-terminal acetylated 17-23 fragment (Ac-LKKTETQ) that encompasses the essential actin-binding domain responsible for the peptide’s primary biological activities. This remarkable molecule functions as the principal G-actin sequestering protein in mammalian cells, maintaining approximately 500 μM intracellular concentrations that far exceed typical peptide hormone levels.
