Description

Somatotropin Fragment 87-124 is a defined synthetic peptide sequence corresponding to a specific bioactive region of human growth hormone (hGH). This high-purity fragment is critical for advanced biochemical research and pharmaceutical development, offering a precise tool for studying hormone-receptor interactions and metabolic pathways. It is primarily utilized by research institutions, diagnostic kit manufacturers, and biopharmaceutical companies engaged in endocrinology, peptide therapeutics, and assay development.

Application

• Biochemical Research: Used as a reference standard and active agent in studies of growth hormone signaling, receptor binding affinity, and structure-activity relationships (SAR).
• Diagnostic Development: Serves as a critical antigen or calibrator in the development and validation of immunoassays (ELISA, RIA) for detecting growth hormone or related antibodies.
• Pharmaceutical R&D: Employed in the design and screening of novel peptide-based therapeutics, growth hormone secretagogues, or receptor antagonists.
• Cell Culture & Bioassay: Applied in in vitro cell-based assays to stimulate or study specific growth hormone-mediated cellular responses and proliferation.
• Antibody Production: Acts as an immunogen for generating specific polyclonal or monoclonal antibodies against the hGH 87-124 epitope.

Quality Control

Our Somatotropin Fragment 87-124 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). We provide full traceability and Certificates of Analysis (COA) detailing purity, peptide content, and impurity profiles to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This product is hygroscopic (moisture-sensitive). Allow the vial to reach room temperature in a desiccator before opening to minimize moisture absorption. For long-term storage, consider under inert atmosphere.
