Big Gastrin (G-34) is a highly purified human peptide hormone composed of 34 amino acids. Synthesized to match the endogenous form secreted by gastric G cells, this peptide plays a critical role in stimulating gastric acid secretion and regulating digestive physiology. Its extended sequence compared to smaller gastrin isoforms makes it a valuable tool for studying receptor binding kinetics, post-translational modifications, and hormone-receptor interactions in gastrointestinal research.

This product is ideal for researchers investigating gastrin-mediated signaling pathways, CCK-B receptor pharmacology, and endocrine tumor biology. Big Gastrin has been implicated in various physiological and pathological processes, including acid hypersecretion, colorectal carcinoma progression, and ghrelin modulation. Its high purity and sequence fidelity support reproducible results in ELISA calibration, immunohistochemistry, and in vitro bioassays.

Each batch is rigorously characterized and supplied lyophilized for long-term stability. The peptide is Research Use Only (RUO) and not intended for diagnostic or therapeutic applications. For safety and handling, refer to the MSDS.

Key Features:

  • Human Big Gastrin (G-34) peptide, 34 amino acids
  • High purity, suitable for receptor binding and bioactivity studies
  • CAS #: 60675-77-6; Molecular Mass: 3849.2 g/mol
  • Validated for use in gastric hormone research and oncology models
  • RUO designation: not for clinical or therapeutic applications

Indication for Use:
This product is for Research Use Only (RUO). It is not intended for human or animal use, diagnostic procedures, or therapeutic applications.
