Description

(β-Asp3)-Grf (Human) Trifluoroacetate Salt is a high-purity synthetic peptide derivative of human growth hormone-releasing factor (GRF). This compound is a critical research-grade biochemical for studying growth hormone secretion mechanisms and related metabolic pathways. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and biotechnology companies focused on endocrinology and peptide-based therapeutic development.

Application

• Biomedical Research: A key reference standard and active agent in studies investigating the physiology and pharmacology of growth hormone release.
• Pharmaceutical Development: Serves as a precursor or intermediate in the research and development of novel peptide therapeutics targeting growth disorders.
• In Vitro Assays: Used in cell-based assays and receptor binding studies to evaluate the potency and specificity of GRF analogs.
• Metabolic Studies: Employed in preclinical research to understand the role of GRF in metabolism, aging, and muscle development.
• Quality Control: Acts as a certified reference material (CRM) for the analytical testing and validation of related peptide products in QC laboratories.

Quality Control

Our (β-Asp3)-Grf (Human) Trifluoroacetate Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). A detailed Certificate of Analysis (COA) providing batch-specific results is supplied with every order to ensure traceability and compliance with research-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, consider under an inert atmosphere.
