Description

22-34-Gastrin I (Pig), 22-L-Leucine- is a specific, high-purity peptide fragment derived from porcine gastrin, a key regulatory hormone. This compound is essential for advanced biochemical research and pharmaceutical development, particularly in studies of gastrointestinal physiology and hormone-receptor interactions. It is primarily utilized by research institutions, diagnostic manufacturers, and biopharmaceutical companies engaged in metabolic research and peptide-based drug discovery.

Application

• Biochemical Research: A critical reference standard and tool for investigating the structure, function, and metabolic pathways of gastrin and related gastrointestinal hormones.
• Pharmaceutical R&D: Used in the development and screening of novel therapeutic agents targeting gastrin receptors for conditions like peptic ulcers and certain cancers.
• Diagnostic Development: Serves as a key antigen or calibrator in the production of immunoassays and diagnostic kits for measuring gastrin levels in clinical samples.
• Metabolic Studies: Employed in physiological studies to understand the role of gastrin fragments in gastric acid secretion and mucosal growth.
• Peptide Chemistry: Used as a building block or intermediate in the custom synthesis of longer peptide sequences for specialized research applications.
