IGF-1 LR3

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg³) is a recombinant polypeptide analog of native human IGF-1 that incorporates a substitution of arginine at position 3 along with an extended N-terminal sequence. These structural modifications alter binding interactions with endogenous IGF-binding proteins and distinguish IGF-1 LR3 from unmodified IGF-1. In laboratory research settings, IGF-1 LR3 is utilized as a reference material for studying IGF-related receptor interactions, signaling cascades, and comparative structure–activity relationships within insulin-like growth factor pathways.
