Description

Somatotropin (1-43) is a bioactive peptide fragment derived from the N-terminal region of human growth hormone. This specific sequence is of significant interest for research into the structure-activity relationships and receptor binding mechanisms of somatotropin. It serves as a critical reference standard and intermediate for researchers and developers in the fields of endocrinology, peptide therapeutics, and biochemical analysis.

Application

• Biochemical Research: Used as a reference standard in studies investigating the biological activity and receptor interaction of growth hormone fragments.
• Pharmaceutical Development: Serves as a key intermediate or analytical standard in the research and development of novel peptide-based therapeutics and diagnostics.
• Analytical Chemistry: Employed as a high-purity calibrant in chromatographic (HPLC, UPLC) and mass spectrometric methods for quantitative analysis.
• Academic Studies: Utilized in university and institutional labs for teaching and advanced research on protein structure, function, and peptide synthesis.
