Reagents Verified with Peptide Works (7)
BPC-157
Body Protection Compound-157 Pentadecapeptide
BPC-157 is a stable 15-amino acid synthetic pentadecapeptide fragment originally derived from human gastric juice protein BPC. Evaluated in UK academic and biotechnology laboratories as an analytical benchmark for focal adhesion kinase (FAK) activation and endothelial tube formation assays.
TB-500
Thymosin Beta-4 Active Hexapeptide Domain (Ac-LKKTET-OH)
TB-500 represents the synthetic active fragment of Thymosin Beta-4, a major physiological actin-sequestering protein. Studied in British biomedical research for its ability to regulate G-actin polymerization, promote keratinocyte migration, and downregulate myofibroblast differentiation.
Semax
Heptapeptide ACTH(4-10) Analog (Met-Glu-His-Phe-Pro-Gly-Pro)
Semax is a synthetic regulatory heptapeptide structurally derived from an adrenocorticotropic hormone fragment (ACTH 4-10) stabilized with a C-terminal Pro-Gly-Pro tripeptide. Examined in neuropharmacology laboratories for its modulation of BDNF, trkB receptors, and cerebral monoamines.
Selank
Synthetic Tuftsin Heptapeptide Analogue (Thr-Lys-Pro-Arg-Pro-Gly-Pro)
Selank is a synthetic regulatory heptapeptide derived from the immunomodulatory tetrapeptide tuftsin, extended with a C-terminal Pro-Gly-Pro tripeptide. Examined in neuroimmunology laboratories for its allosteric modulation of GABAA receptors, enkephalinase inhibition, and IL-6 expression.
Epithalon
Synthetic Pineal Tetrapeptide (Ala-Glu-Asp-Gly)
Epithalon (Epitalon) is a synthetic tetrapeptide modeled on the endogenous pineal extract epithalamin. Studied extensively in biogerontology laboratories for its ability to overcome the Hayflick limit via telomerase catalytic subunit (hTERT) transcription and chromatin remodeling.
Tirzepatide
Dual GIP and GLP-1 Receptor Co-Agonist 39-AA Synthetic Peptide
Tirzepatide is a synthetic 39-amino-acid unimolecular dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor co-agonist conjugated to a C20 fatty diacid moiety. Studied extensively in UK biochemical and pharmaceutical research for receptor affinity dynamics.
Semaglutide
Acylated GLP-1 Analogue (31-AA Chain with C18 Diacid Spacer)
Semaglutide is a synthetic long-acting glucagon-like peptide-1 (GLP-1) receptor agonist modified at position 8 with alpha-aminoisobutyric acid (Aib) and acylated at Lys26 with a C18 fatty diacid chain. Studied in UK endocrinology and metabolic research as a classical mono-incretin reference standard.
