Description

R3 Igf-I is a synthetic peptide analog of Insulin-like Growth Factor I (IGF-I), a critical hormone involved in cellular growth, development, and metabolism. This high-purity compound is essential for advanced research and development in life sciences, offering a reliable and consistent tool for studying growth pathways. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and biotechnology companies focused on metabolic disorders, cell culture applications, and therapeutic development.

Application

• Biomedical Research: Used as a key reagent in studying cell proliferation, differentiation, and apoptosis signaling pathways.
• Pharmaceutical Development: Serves as a reference standard or active pharmaceutical ingredient (API) intermediate in the development of growth hormone-related therapies.
• Cell Culture & Tissue Engineering: Employed as a growth factor supplement in serum-free media formulations to support the growth of specific cell lines.
• Metabolic Studies: Applied in research models to investigate the role of IGF-I in glucose metabolism, insulin sensitivity, and related disorders.
• Biochemical Assay Development: Utilized as a calibrant or target molecule in the development of immunoassays (e.g., ELISA) and binding studies.

Quality Control

Our R3 Igf-I is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and mass spectrometry for identity confirmation, to ensure it meets rigorous research-grade specifications. Certificates of Analysis (COA) detailing purity, endotoxin levels, and biological activity are provided to guarantee batch-to-batch consistency and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized powder at -20°C or below. Once reconstituted, aliquot and store at -20°C to -80°C. Avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure the container is sealed under anhydrous conditions after each use.
