Description

Igf-1 Lr3 CAS NO 946870-92-4 is a long-acting synthetic analog of Insulin-like Growth Factor 1 (IGF-1), engineered for enhanced stability and biological activity. This engineered peptide is critical for research and development in life sciences due to its potent mitogenic and anabolic properties. It is primarily utilized by biotechnology firms, academic research institutions, and pharmaceutical developers focused on metabolic studies, muscle regeneration, and advanced cell culture applications.

Application

• Biomedical Research: Used as a key reagent in studies investigating cell proliferation, differentiation, and apoptosis signaling pathways.
• Pharmaceutical Development: Serves as a reference standard or active candidate in pre-clinical research for metabolic and musculoskeletal disorders.
• Cell Culture & Tissue Engineering: Employed as a growth supplement in serum-free media formulations for cultivating specialized cell lines.
• Metabolic Studies: Applied in research models to study glucose uptake, protein synthesis, and the mechanisms of the GH/IGF axis.
• Performance & Recovery Research: Investigated in models related to muscle hypertrophy, tissue repair, and recovery from atrophy.

Quality Control

Our Igf-1 Lr3 is manufactured under stringent conditions to ensure the highest standards of purity and biological activity. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, potency, and sterility data. We adhere to relevant quality management systems suitable for research-grade biopharmaceuticals.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized powder at -20°C or below. Reconstituted solutions should be aliquoted and stored at -20°C to -80°C to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive).
