Description

Grf (1-44) (Human) is a synthetic peptide fragment corresponding to the human growth hormone-releasing factor. This compound is a critical research tool for studying the mechanisms of growth hormone secretion and regulation. It is essential for researchers and developers in the fields of endocrinology, peptide chemistry, and pharmaceutical development. The product is supplied under the CAS registry number 90599-39-6.

Application

• Biochemical Research: Used as a reference standard and active agent in studies of the hypothalamic-pituitary axis and growth hormone (GH) release mechanisms.
• Pharmaceutical Development: Serves as a key intermediate or lead compound in the development of diagnostic agents and potential therapeutics for growth disorders.
• In Vitro Assays: Employed in cell-based assays and receptor binding studies to investigate GRF receptor activity and signal transduction pathways.
• Antibody Production: Acts as an immunogen for generating specific antibodies used in immunoassays (ELISA, RIA) and immunohistochemistry.
• Quality Control: Utilized as a system suitability standard in analytical methods (e.g., HPLC, MS) for related peptide pharmaceuticals.
