IGF-1 LR3 1mg

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a synthetically engineered analog of native IGF-1, designed to enhance molecular stability and prolong biological activity within controlled research environments. Structural modifications—including an arginine substitution at position 3 and the addition of a 13-amino-acid extension—significantly reduce binding affinity to IGF-binding proteins (IGFBPs). This reduced sequestration results in prolonged receptor availability and extended signaling duration, with experimental observations indicating an activity window up to 100–120 times longer than that of unmodified IGF-1 under certain conditions.

The increased bioavailability of IGF-1 LR3 enables sustained investigation of downstream cellular signaling pathways without the rapid degradation typically associated with endogenous IGF-1. In preclinical and in vitro models, it is widely utilized to examine mechanisms related to cellular proliferation, metabolic regulation, protein synthesis pathways, and tissue-repair processes. Its stability and receptor interaction profile make it particularly valuable for studies requiring extended signaling kinetics and reduced interference from endogenous binding proteins.

Formulated at 1 mg, IGF-1 LR3 provides a standardized and practical concentration suitable for a range of experimental applications, including cell-based assays, mechanistic pathway analyses, and stress-response modeling. Its enhanced receptor interaction dynamics, coupled with minimal IGFBP interference, support detailed exploration of growth factor–mediated signaling cascades, metabolic responses, and regenerative biology in controlled laboratory settings.

This material is produced in accordance with stringent purity specifications and is manufactured as both an LPS-free and endotoxin-free peptide to minimize confounding variables in sensitive assays. Comprehensive endotoxin testing is conducted to ensure consistency, reproducibility, and reliability across research applications, without implication of clinical or therapeutic use.
