The 15-amino acid sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) has no known sequence homology with other characterized peptides in the Protein BLAST database, making it structurally unique among gastric peptides.\u003c\/p\u003e\n\u003cp\u003eBPC-157 is a linear peptide lacking disulfide bonds, freely soluble in water at physiological pH, and notably stable under conditions that degrade most peptides — including prolonged exposure to gastric acid. The compound is metabolized through standard peptide pathways, with the final metabolite being individual amino acids (primarily proline).\u003c\/p\u003e\n\u003ch3\u003eResearch Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAngiogenic signaling and VEGFR2-associated pathway investigation\u003c\/li\u003e\n\u003cli\u003eNitric oxide (NO) system modulation and endothelial function studies\u003c\/li\u003e\n\u003cli\u003eFAK-paxillin and JAK-2 signaling cascade research\u003c\/li\u003e\n\u003cli\u003eGrowth hormone receptor expression studies in fibroblast models\u003c\/li\u003e\n\u003cli\u003eEGR-1 (Early Growth Response gene 1) and ERK1\/2 pathway activation\u003c\/li\u003e\n\u003cli\u003eCytoprotective and mucosal integrity research in gastrointestinal cell lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePublished Research Context\u003c\/h3\u003e\n\u003cp\u003eBPC-157 has been referenced in over 150 published studies spanning multiple organ systems and model organisms since its first description by Sikiric et al. in the early 1990s at the University of Zagreb. Preclinical literature has documented investigations across vascular, gastrointestinal, musculoskeletal, and neurological experimental models. The peptide has been shown to upregulate growth hormone receptor expression in tendon fibroblasts in a dose- and time-dependent manner, with downstream JAK-2 phosphorylation confirmed (Chang Gung University, 2018). Pharmacokinetic profiling (Frontiers in Pharmacology, 2022) confirmed standard peptide drug metabolism with no novel or toxic metabolites detected.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Formula:\u003c\/strong\u003e C62H98N16O22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 1,419.56 g\/mol\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSequence:\u003c\/strong\u003e GEPPPGKPADDAGLV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 137525-51-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e White lyophilized powder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e Lyophilized, −20°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥98% by HPLC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolubility:\u003c\/strong\u003e Freely soluble in water\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e⚠ For in-vitro research use only.

It is the most abundant member of the beta-thymosin family and functions as the principal actin-sequestering molecule in most eukaryotic cell types. Intracellular concentrations can reach up to 0.5 mM, reflecting its fundamental role in cytoskeletal regulation.\u003c\/p\u003e\n\u003cp\u003eThe peptide forms a 1:1 complex with G-actin (globular actin), opposing polymerization into F-actin (filamentous actin) and effectively buffering the monomeric actin pool. The conserved LKKTET motif at positions 17–22 is frequently cited as the primary actin-binding domain, though crystallographic modeling shows that essentially the entire length of the sequence interacts with actin in the complex. TB-500 does not bind to the extracellular matrix and has a low molecular weight, allowing it to travel through tissues efficiently.\u003c\/p\u003e\n\u003ch3\u003eResearch Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eActin polymerization dynamics and cytoskeletal remodeling studies\u003c\/li\u003e\n\u003cli\u003eCell migration, morphology, and motility assays\u003c\/li\u003e\n\u003cli\u003eAngiogenesis research — identified as a gene upregulated 4–6 fold during early blood vessel formation\u003c\/li\u003e\n\u003cli\u003eEpicardial progenitor cell activation and cardiac remodeling models\u003c\/li\u003e\n\u003cli\u003eAnti-inflammatory pathway investigation (oxidized Tβ4 sulfoxide derivative)\u003c\/li\u003e\n\u003cli\u003eWound fluid composition analysis and extracellular matrix signaling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePublished Research Context\u003c\/h3\u003e\n\u003cp\u003eThymosin Beta-4 was originally isolated from calf thymus and was the second peptide from Thymosin Fraction 5 to be fully sequenced and synthesized. Its role extends well beyond immune function: research at multiple institutions has demonstrated diverse effects in tissue regeneration models. Phase 2 clinical trials in patients with pressure ulcers, venous ulcers, and epidermolysis bullosa showed accelerated repair rates with favorable safety profiles. Notably, Glasgow University researchers (1999) identified the Tβ4 sulfoxide derivative as having multiple anti-inflammatory effects on neutrophils, including reduced adhesion to endothelial cells. The peptide is highly conserved across mammalian species, underscoring its fundamental biological significance.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Formula:\u003c\/strong\u003e C212H350N56O78S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 4,963 g\/mol\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSequence Length:\u003c\/strong\u003e 43 amino acids\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGene:\u003c\/strong\u003e TMSB4X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Motif:\u003c\/strong\u003e LKKTET (positions 17–22)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e White lyophilized powder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e Lyophilized, −20°C, desiccated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥98% by HPLC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e⚠ For in-vitro research use only.
