TB-500 (Thymosin Beta-4) 10mg (43aa)

TB-500 2mg (43aa): Investigating the Pillars of Actin-Mediated Regeneration

TB-500, or synthetic Thymosin Beta-4 (T$beta$4), is a cornerstone of peptide science, functioning as the primary G-actin sequestering protein in nearly all mammalian cells. The 43-amino acid (43aa) sequence provided here is the full-length molecule, distinguished from the shorter 7-amino acid fragments by its ability to modulate systemic cellular behavior. Researchers looking to buy TB-500 2mg online trust Peptide Sciences for the structural integrity and sequence accuracy required to investigate the complex signaling pathways of tissue repair and cellular motility.

What is TB-500 (Thymosin Beta-4)?

Thymosin Beta-4 is a 43-amino acid polypeptide ($MW approx 4921$ g/mol) that plays a critical role in the organization of the cytoskeleton. By binding to globular actin (G-actin) in a 1:1 ratio, TB-500 prevents its polymerization into filamentous actin (F-actin), effectively acting as a buffer that regulates cell morphology and movement. Its sequence homology to human T$beta$4 allows it to initiate a signaling cascade that promotes angiogenesis and reduces systemic inflammation in advanced research models.
