Description

Grf (1-44) (Human) is a synthetic peptide fragment corresponding to the human growth hormone-releasing factor (GRF). This high-purity peptide is critical for research and development in endocrinology and metabolic studies. It serves as a key reference standard and active pharmaceutical ingredient (API) intermediate for scientists and manufacturers in the pharmaceutical and biotechnology sectors. Its precise structure enables targeted investigation of growth hormone secretion mechanisms.

Application

• Pharmaceutical Research & Development: Used as a reference standard and key intermediate in the development of diagnostic assays and therapeutic agents targeting growth hormone disorders.
• Biochemical Research: Essential for in vitro and in vivo studies investigating the mechanisms of growth hormone secretion, receptor binding, and signal transduction pathways.
• API Synthesis: Serves as a critical building block in the solid-phase or solution-phase synthesis of larger, more complex GRF analogs and related peptide hormones.
• Quality Control & Validation: Employed as a certified reference material (CRM) to validate analytical methods such as HPLC and mass spectrometry in quality control laboratories.
