BPC-157 + TB-500 Blend

This blend combines two synthetic peptides widely used as reference materials in regenerative and cytoprotective signaling research. BPC-157 is a stable pentadecapeptide (15 residues, sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val; C62H98N16O22; ~1419.5 g/mol; CAS 137525-51-0) derived from a sequence in gastric juice protein. TB-500 is the N-acetylated heptapeptide Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln (C39H67N9O13; ~878 g/mol), corresponding to the actin-binding active fragment (residues 17-23) of thymosin beta-4.

The two components are co-formulated to support in vitro and ex vivo investigation of overlapping repair-associated pathways. Research areas include models of tissue repair and angiogenesis, fibroblast and endothelial cell migration assays, actin cytoskeleton dynamics, extracellular matrix remodeling, and cytoprotective signaling. Supplied strictly as a characterized reference material for laboratory research use only; not for diagnostic, therapeutic, or human or veterinary use.

Store lyophilized powder at -20C protected from light and moisture; stable for extended periods when sealed. After reconstitution, store at 2-8C and use within a limited period; avoid repeated freeze-thaw cycles. For long-term storage of reconstituted material, aliquot and store at -20C or below.

Reconstitute in sterile bacteriostatic or ultrapure water; both peptides are water-soluble. Aliquot after reconstitution to minimize freeze-thaw exposure. Certificate of Analysis with HPLC and MS data available per lot.
