IGF-1 LR3 1mg

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic analog of human Insulin-like Growth Factor-1 (IGF-1) engineered to enhance stability and extend biological persistence under research conditions. Compared with native IGF-1, IGF-1 LR3 incorporates two structural modifications: an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus. These modifications are designed to reduce binding affinity to IGF-binding proteins (IGFBPs) while significantly prolonging the peptide's half-life relative to native IGF-1.

In research settings, IGF-1 LR3 has been utilized as a tool for investigating IGF-1 receptor signaling, cellular growth and differentiation pathways, protein synthesis mechanisms, and peptide pharmacology. Its enhanced stability and prolonged activity make it valuable for studies examining receptor activation, intracellular signaling cascades, tissue biology, metabolic regulation, and peptide engineering. IGF-1 LR3 continues to serve as an important research compound in cellular and molecular biology, supporting investigations into the complex physiological roles of the IGF signaling pathway. Acetic Acid is a sterile, research-grade acidic solvent widely utilized in laboratory environments for solution preparation, pH adjustment, peptide reconstitution, and analytical applications. Due to its well-characterized chemical properties and broad compatibility with numerous research compounds, acetic acid serves as an essential reagent across multiple scientific disciplines, including biochemistry, molecular biology, peptide research, and pharmaceutical development.

Research Use Only
This product is intended solely for in vitro laboratory research purposes. It is not approved for human or animal use and must not be used in food, dietary supplements, pharmaceuticals, or cosmetic applications. All products arrive in lyophilized (freeze-dried) powder form.

Peptide Storage Guidelines

For optimal stability, lyophilized (freeze-dried) peptides should be stored in a cool, dry place when intended for short-term use. For long-term storage, refrigeration or freezing is recommended to help maintain peptide integrity and stability.

Amino Solutions are shelf-stable and should be stored at room temperature in a cool, dry location. Refrigeration is not recommended unless otherwise specified.

Bacteriostatic Water should also be stored in a cool, dry place at room temperature. Refrigeration may contribute to the formation of cloudiness or visible particulates, which can complicate peptide reconstitution procedures conducted for research purposes.

To preserve product quality, always keep protected from excessive heat, moisture, and direct sunlight.
